The uplifting end of the world video scene was included by the filmmakers when they found out that one of the news networks actually had such a video prepared to run in case of the end of the world. CNN has a video for this purpose in its archive, and its staff are instructed to "hold the video for release until the end of the world is confirmed."

In a deleted scene, the Gremlins release all of the animals in the "Splice o' Life" lab. During the filming of this scene, the monkeys in the lab set were genuinely so terrified of the Gremlin puppets, that they refused to leave their cages when their trainers called for them.

The opening aerial shot of New York City was stock footage from Superman IV - Die Welt am Abgrund (1987).

The filmmakers chose John Rambo as the character that Gizmo was going to imitate in this movie. The permission for their use was granted by Sylvester Stallone.

Unlike the "PG" rated predecessor, the MPAA rated this movie "PG-13". It should be noted that Gremlins - Kleine Monster (1984) is one of the movies that helped to create the PG-13 rating.

Leonard Maltin appears as himself repeating his criticisms of Gremlins - Kleine Monster (1984) while he holds a video version of the movie. However, his rant is cut short when gremlins pounce on him as a result. In his annual Movie Guide, he gave this movie three stars (out of a possible four) and refers to this scene as a "gratuitous cameo", though he doesn't say he's actually in the movie.

At one point in this movie, Director Joe Dante attempted to involve his audience in the story by making it seem as if the gremlins had taken over whatever theater in which this movie would be screened. This sequence was inspired by a similar stunt in William Castle's Schrei, wenn der Tingler kommt (1959). During his DVD commentary for this movie, Dante recalled that Warner Brothers wanted the sequence cut, as they were concerned the audience would believe the film actually had malfunctioned, test screening ultimately proved otherwise. However, the video version caused problems: Instead of film-breaking effects, the scene looked like a VHS malfunctioning. Many rental copies were returned as a result of this, and video mastering houses called the filmmakers to ask them if this was intentional.

The mother scolding the theater manager regarding the movie's inappropriate tone for children was based in fact. During a screening of Gremlins - Kleine Monster (1984), Director Joe Dante really was severely criticized by a mother who walked out of the theater with her daughter during the infamous kitchen massacre sequence. The daughter begged to be let back in the theater, got free from the mother, and hid in the theater to watch the rest of the movie.

When Sir Christopher Lee was cast in this movie, one of the first things he did was apologize to Director Joe Dante (who also directed Das Tier (1981)) for appearing in Das Tier II (1985).

Director Joe Dante prefers this movie to Gremlins (1984).

Mohawk was a re-creation of Stripe from Gremlins (1984), and was voiced by the same actor.

Aside from Mohawk, the other three Mogwai created from Gizmo are called George, Lenny, and Daffy (the first two referring to John Steinbeck's novel "Of Mice And Men", the latter referring to Daffy Duck).

In the original script, Randall Peltzer was to return after the gremlins were killed at the end, and give to Gizmo his newest "invention": a wet-suit like thing that would prevent Gizmo from ever getting wet again, therefore preventing any sort of gremlin problems in the future (provided it never ate after midnight). The scene was all set to shoot, and Hoyt Axton was available to shoot the scene. But, the filmmakers figured that the movie was already running too long, and they'd never use the scene anyway, so it was never shot.

In the cartoon intro, Daffy Duck says to Bugs: "Fifty years of you hogging the spotlight is enough." This movie was released the year of Bugs Bunny's 50th birthday.

Originally, Executive Producer Steven Spielberg wanted to cut the scene when a boy crosses the "Police Line" banner outside Clamp Tower. He changed his mind when Director Joe Dante revealed to him that this boy was his nephew.

Director Joe Dante told Cahiers du Cinéma in 1990, that Warner Brothers opened this movie directly opposite Dick Tracy (1990) in an attempt to keep the box-office record set by Batman (1989) from being broken.

Gizmo refers to Mr. Wing as "Keye Luke", which is, of course, the actor's real name.

The movie that Grandpa Fred (Robert Prosky) presents in his show as "The Attack of the Octopus People" is, in fact, Oktaman - Die Bestie aus der Tiefe (1971), which featured the first costume designed by Rick Baker.

When Gizmo first sees the janitor (John Astin), he says "Gomez", referring to Die Addams Family (1964) character made famous by Astin.

After Gremlins - Kleine Monster (1984) became such a surprise success, Warner Brothers immediately wanted a sequel, but Director Joe Dante had had enough Gremlins for a while and declined. Work on this movie proceeded without him, as the studio approached various directors and writers. Storylines considered included sending the gremlins to cities like Las Vegas or even the planet Mars. After these ideas fell through, the studio finally asked Dante again, who agreed on the condition that he be allowed to do anything he wanted. He also received a bigger budget. In the DVD commentaries for Gremlins (1984) and this movie, Dante stated that he felt that this movie was a case of waiting too long to capitalize on the success of Gremlins (1984), which hurt this movie's chances of success.

The character of Grandpa Fred was based on Al Lewis' character (Grandpa Munster) in the television series Die Munsters (1964). In the 1980s, Lewis (as Grandpa Munster) hosted a show on TBS, called "Super Scary Saturday", where he would show old monster movies, just as Fred does in this movie.

For the special effects, Director Joe Dante turned to Rick Baker, when Chris Walas and Rob Bottin had to turn it down. Initially, Baker was not interested, as he saw this movie as too much work for a project in which he would not be the creator, but rather a successor to Walas. He was eventually persuaded to accept the job when it was suggested he could make the Gremlins and Mogwai more diverse.

When Billy is trying to explain the rules regarding the mogwai to Forster's staff, they find them quite absurd and interrogate him on the application of this rules. This scene originates from the fact that the filmmakers themselves saw the rules as irrational, and some questions in the scene were based upon queries raised by fans of Gremlins - Kleine Monster (1984).

At one point, one of the ideas for the ending of the movie was that the gremlins were supposed to be killed by Daniel Clamp filling the building up with cement. That was until the animators discovered that they had the technology to create an "electrical" Gremlin, which they realized could improve the storyline (and its ending).

The face of one of the Gremlins, the one who turns on the microwave during the cooking segment, was modelled after The Kraken, from Clash of the Titans (1981).

The scene where Gizmo dances to "I'm Ready" by Fats Domino was originally supposed to feature "Dancing With Myself" by Billy Idol. The filmmakers were unable to get permission to use the Idol song, so they found another song with the same beat.

Most of the scenes where Gizmo (or the other mogwai) were on their own, were filmed with double scale puppets.

In the scene where Mohawk drinks a potion which enables him to change into a centauroid spider, the pulsating sound effect from Tarantula (1955) can be heard. The effect was originally recorded for the Martian war machines in Kampf der Welten (1953). The heavy metal song that plays in the background is one of the guitar solos from the band Slayer's 1986 song, "Angel of Death".

In a corridor of the Clamp Tower, one nameplate says "Vectorscope Labs". This is a reference to the movie Die Reise ins Ich (1987) also directed by Joe Dante.

There is a sample of the action music from Meine teuflischen Nachbarn (1989), also directed by Joe Dante and composed by Jerry Goldsmith, when the Bat Gremlin flies out of the Clamp Tower after being injected with the sunblock solution.

Chris Walas, who created the Gremlins in the first movie, declined the opportunity to create them again, choosing instead to create the effects for and direct Die Fliege II (1989).

Chuck Jones was lured out of retirement to provide the cartoon segment in this movie.

When this movie made its debut on home video, the filmmakers altered the film-breaking scene, to make it seem as if VCRs had been broken by the gremlins. This time John Wayne (in footage from Chisum (1970)) forces the gremlins into continuing the movie, although voice impersonation was needed since Wayne had been dead since 1979. Wayne's son, Michael Wayne, recommended Chad Everett for the voice. Notably, a clip from Kommt ein Häschen geflogen (1943), featuring Bugs Bunny and a different, cartoon gremlin, appears in this version.

Among the changes in the original script was that Daniel Clamp (John Glover) evolved from being the central villain into kind of a nice guy, while the character played by Robert Picardo took over most of the villain's role.

Tim Curry was considered for the voice of the Brain Gremlin.

Several gremlins hiccuping are archive recordings of Mel Blanc's hiccups from various Looney Tunes shorts.

The movie that the gremlins George and Lenny are watching in the systems control center is Panik in New York (1953).

Chris Columbus was unavailable to write the script due to him directing Kevin - Allein zu Haus (1990).

WILHELM SCREAM: As a victim is covered in gremlins and he falls off of a ledge.

Robert Picardo controlled Greta, the "female" gremlin when it was attached to him instead of the puppeteers, because the puppet had so much contact and movements with his character. This technique is also used in the scene where Daniel Clamp (John Glover) pushes the gremlin in the paper shredder.

At one point, Director Joe Dante, Producer Michael Finnell, Executive Producer Steven Spielberg, and Screenwriter Charles S. Haas thought what the movie needed was some kind of S.W.A.T. team character, a soldier of fortune who could come in during the fourth act, and there would be a lot of Road Runner-Coyote gags between this guy and the Gremlins. Charles Napier was their first choice for this character.

The original version of this movie was longer, but Executive Producer Steven Spielberg, after the first screening, claimed there were too many gremlins, and several scenes were cut as a result.

In a deleted scene, three of the main gremlins (George, Lenny, and Daffy) sneaking into Grandpa Fred's (Robert Prosky's) studio and "help" him host, which worked because Grandpa Fred's show was supposed to be scary. A still from this scene was used on the video cover.

When Kate arrives to Billy's office looking for Gizmo, she finds mogwai Daffy on the top of the Clamp Tower model playing with some airplane toys located over him. This is an homage to King Kong und die weiße Frau (1933).

In a deleted scene, Dr. Catheter (Sir Christopher Lee) examines a bat injected with the sunblock solution. He then says to Wally, "I'm told they sometimes feed on blood". This was a reference to Lee's performances as Count Dracula in the Hammer Film Productions horror movies.

As the Bat Gremlin crashes through the wall, escaping into the city, it leaves a hole in the shape of the Batman symbol.

Clamp's automatic office doors open and sound the same as the doors of the U.S.S. Enterprise NCC-1701 from Raumschiff Enterprise (1966).

For the Italian version of the movie, notorious Italian art critic Vittorio Sgarbi gave his voice to the Brain Gremlin.

The twin brother scientists in the movie were named Martin and Lewis, a reference to the famous Jerry Lewis and Dean Martin. (The twin brothers were also in Terminator 2: Judgment Day (1991), as the cop in the mental institution getting coffee from the vending machine in the lobby and as his T-1000 clone.)

Ranked #33 in Empire Magazine's "50 Greatest Ever Movie Sequels" (2009).

DIRECTOR TRADEMARK (Joe Dante):(Looney Tunes Sound Effects): Sound effects lifted from classic Warner Brothers cartoons are used frequently throughout this movie.

The character of Daniel Clamp was a caricature of real estate mogul and President Donald J. Trump.

There's a scene where a voice says "You know, I've been thinking, Mr. Clamp would make a great President." This scene didn't make it to the final cut, but it appears as a deleted scene on the Blu-ray and DVD editions.

Director Joe Dante claimed that the gremlins musical number is a shameless steal from the movie Broadway-Show (1934), another Warner Brothers release.

Composer Jerry Goldsmith also wrote the music for Rambo: First Blood Part II (1985). In this movie, John Rambo claims, "to survive a war, you gotta become war." These words inspire Gizmo to stand up against Mohawk.

Daniel Clamp is a parody of New York City billionaire (and President) Donald J. Trump, with media aspects of the Clamp empire being based on Ted Turner.

This movie is bookended by animated segments featuring Bugs Bunny and Daffy Duck. Director Joe Dante featured Bugs and Daffy in Looney Tunes: Back in Action (2003).

By the time of this movie's theatrical release in June of 1990, despite wearing the WWF Championship belt in his brief cameo, Hulk Hogan was no longer the reigning champion.

In a corridor of the Clamp Tower, one nameplate says "Dr. Quatermass". Quatermass is the main character in several British television series and movies, including The Quatermass Experiment (1953).

In the scene where they go to the Canadian restaurant, the phrase "Gretzky party of six, eh" can be heard on the restaurants intercom system, a reference to famous Canadian hockey player Wayne Gretzky and Canadians penchant for using the phrase "eh" at the end of their sentences.

With the intervening advancements in special effects technology from Gremlins (1984), the gremlins are much more animated in this movie, and are seen walking and dancing.

The trailer was narrated by Percy Rodrigues.

Suggested by Director Jonathan Kaplan, Director Joe Dante hired Charles S. Haas to write the screenplay.

After Die Reise ins Ich (1987), this movie marked the fourth collaboration between Director Joe Dante and Producer Michael Finnell with Executive Producer Steven Spielberg.

Scenes from It's a Wonderful Life (1946) can be seen on one of the screens in Clamp's (John Glover's) office.

The same year, Robert Picardo did voice work on the Arnold Schwarzenegger science fiction action thriller Total Recall (1990), in which he provide the voice of Johnny Cab.

In the original opening of this movie, Bugs Bunny tells Daffy Duck that he has been promoted to an executive, and Bugs puts Duffy in charge of the movie's titles and gets Daffy to type the movie's title onto a computer screen, which Daffy writes the title wrong before Bugs corrects it and Daffy quits and resigns.

Bugs Bunny and Daffy Duck appearing in the Looney Tunes opening was to set the tone for this movie and to tell the audience that this movie was going to be more lighthearted and cartoony than Gremlins (1984), which got a lot of criticism for being too dark.

A billboard of Do the Right Thing (1989) can be seen in the scene in Times Square, next to Burger King.

Sir Christopher Lee appeared with John Astin's stepson Sean Astin and granddaughter Ali Astin in The Lord of the Rings trilogy.

In the novelization for Das Geheimnis des verborgenen Tempels (1985), the inventor, Waxflatter, hallucinates gremlins sabotaging his ornithopter, which is an in-joke to Gremlins - Kleine Monster (1984). Both movies and this movie were Executively Produced by Steven Spielberg.

The scene where the organ-playing phantom Gremlin is unmasked, is an exact replica of the scene from The Phantom of the Opera (1925).

The thirty-first most successful movie of 1990 (as opposed to Gremlins (1984) which ranked number four in the year-end charts for 1984).

John Hora, the Director of Photography (who made his screen acting debut on Die Reise ins Ich (1987), also directed by Joe Dante), appears briefly in the movie, but his scene was cut.

The end credits state that the song "Bombers in the Sky" by Thompson Twins was used in this movie. More accurately, a snippet of the "Razorback! Mix" of this song can be heard when the Mogwai are seen hiding under a table at the Frozen Yogurt stand. The music heard here is not part of the single version of "Bombers in the Sky", meaning listeners only familiar with the original will not recognize it as such.

Jerry Goldsmith's final cameo appearance in a theatrical movie.

Kenneth Tobey (Projectionist) and Sir Christopher Lee (Doctor Catheter) appeared in movie adaptations of John W. Campbell, Jr.'s 1938 novella "Who Goes There?" Tobey played Captain Patrick Hendry in Das Ding aus einer anderen Welt (1951), and Lee played Professor Sir Alexander Saxton in Horror Express (1972).

Bugs Bunny and Daffy Duck appeared at the beginning of this movie and again during the end credits.

There are different two scenes used in the movie when the film messes up mid way in the film. The first one has Hulk Hogan threatening the gremlins to continue or else and second less seen one shown with some of the network versions has a western scene with a John Wayne like character having a shoot out with the gremlins.

John Astin's stepson Sean Astin appeared in Die Goonies (1985), also produced by Steven Spielberg. Gremlins - Kleine Monster (1984) featured another Goonie, Corey Feldman, and was also written by Chris Columbus.

This movie became the second Steven Spielberg project to involve Looney Tunes characters. The first being Who Framed Roger Rabbit (1988), and the third being Tiny Toon Adventures (1990).

The novelization was written by David Bischoff.

This movie is about gremlins taking over a building, and in one scene, Gizmo imitates John Rambo. Sylvester Stallone, who played John Rambo in the Rambo film franchise, passed on the role of John McClane in Die Hard (1988). That movie was about a building that is taken over by terrorists.
