When Princess Poppy is dancing in the large basket costume and gloves, it's a hat-tip to the "bring it on down" characters Justin Timberlake has portrayed on Saturday Night Live (1975).

The original troll doll was created by Thomas Dam from Gjøl in Denmark in 1958. The first ones were filled with wood shavings. Many styles and sizes were made and even animals from donkeys, elephants, giraffes, horses, lions and monkeys. There is even a story about why they are different sizes.

Christine Baranski recorded a song "Bringing Happy Back" to come just after Chef proclaims "I am that he." It was decided that it made Chef too sympathetic a character, as it seems like she genuinely wants to restore happiness to Bergen town, so it was cut. It can be heard on the Blu-ray extras with storyboard drawings.

DreamWorks Animation's first musical film since The Road to El Dorado (2000).

When Poppy and Branch first enter the Bergen castle, they briefly pass by a painting that parodies the famous Norman Rockwell painting "Freedom from Want" which shows a family around the table for Thanksgiving dinner. In this version, it depicts Bergens around the table for the Trollstice feast.

The lead single "Can't Stop The Feeling" was performed at the The Eurovision Song Contest (2016) as an interval act. Justin Timberlake had no idea what the Eurovision Song Contest was before this. The performance also led to speculations that USA would make their debut in the contest by 2017. Dami Im, the Australian representative for the Eurovision Song Contest 2016, provided the voice of Grandma Rosiepuff in the Australian version of the movie.

At the beginning of the movie, a remix of the classical piece "In the Hall of the Mountain King" by Edvard Grieg is playing, while the camera travels through the hall of the Bergen king's castle, which is on top of a mountain. Bergen was also the name of Grieg's hometown, one of the larger cities in Norway.

The music used in this movie and trailer is "Move Your Feet" by the group "Junior Senior", whose members, Jesper Mortensen and Jeppe Laursen, are from Jutland, where the Troll dolls were invented.

Lucky troll dolls were also called "dam dolls," a play on inventor Thomas Dam.

The disco ball seen at the roller rink when Bridget and King Gristle go on their date is the same fake one used by the ogres in Šrekas. Ilgai ir laimingai (2010) to infiltrate Rumplestiltskin's party.

The fanny packs worn by the Bergens are a call back to the style worn in the 80's and 90's when Trolls were at the height of popularity.

This is Anna Kendrick's second collaboration with James Corden and Christine Baranski after Into the Woods (2014).

During Poppy's song in Troll Village, there was a scene where she tries on various dresses (made by the hair-conjoined twins) and says she wants them all. Test audiences felt that it made Poppy seem like a spoiled brat, so it was cut. The scene is on the Blu-ray extras.

This is the Fourth DreamWorks Animation movie to have a female protagonist, after Viščiuku maistas (2000), Monsters vs. Aliens (2009) and Krudžiai (2013).

In 2010 Director Anand Tucker was set to direct a Dreamworks adaptation of the Terry Pratchett 'Bromeliad' trilogy of books (Truckers, Diggers, and Wings). The books focused on a race of tiny humanoids who lived unseen among humans. The lead character of 'Trolls' shares the name 'Masklin' with the lead character of the Bromeliad trilogy. Truckers (1992) had previously been made into a TV Series.

This is the third DreamWorks adaptation that isn't based on a children's book. The first being Anapus tvoros (2006) (which is based on a comic strip) and the second being Ponas Zirnis ir Sermanas (2014) (which is based on a segment on The Bullwinkle Show (1961)).

The scene where prince Gristle rides his tricycle through the halls of the castle looks a lot like Danny Torrance riding his tricycle through the Overlook Hotel in Švytejimas (1980).

When Bridget and Gristle get served their pizza, the music from the arcade game Pac-Man can be heard in the background.

Kunal Nayyar previously worked with Christine Baranski on Didžiojo sprogimo teorija (2007).

Justin Timberlake's second DreamWorks Animation film after Srekas treciasis (2007).

The line "he who controls the trolls controls the kingdom" is more than likely inspired by the line from Frank Herbert's Dune, "whoever controls the spice controls the universe". Or possibly the passage from George Orwell's 1984, "who controls the past controls the future. Who controls the present controls the past."

Jason Schwartzman and Chloë Grace Moretz were attached to star during the film's early stages of development.

One of the first scenes in the movie features young Gristle riding a tricycle through the castle on Trollstice. This entire sequence looks incredibly similar to the opening of the cartoon Bobby's World (1990).

This is also the first time there are no humans in a non-human DreamWorks Animation film that doesn't focus on talking animals. This does not make Antz (1998) or Flushed Away (2006), humanless, as the humans are seen only briefly with no faces shown.

10 year prior to the release of Troliai (2016), fellow DreamWorks Animation film Anapus tvoros (2006) featured a scene with a Troll Doll of which this film is based off.

Walt Dohrn also worked with Mike Mitchell on Šrekas. Ilgai ir laimingai (2010).

At one point in the movie, Branch tells Poppy, "Bad things happen, and there's nothing you can do about it". This exact line was said by the adult Simba in "The Lion King" (1994). Also in both movies the main male lead blames himself for the death of a family member (Simba's father and Branch's grandmother).

After Bridget's date with the King, Branch's ears are a little bit brighter than before. He also smiles. These are signs that Branch had been happy for a while.

When the Trolls escape from Bergentown in the beginning, they use wooden Trolls to disguise their homes. These wooden Trolls resembles Thomas Dam's original Good Luck Trolls toys the film is based on.

In the dance party at the conclusion of the film, Poppy and Branch briefly borrow a few dance steps from Michael Jackson: Thriller (1983).

Body count: 5; King Gristle Sr., the clown troll in the scene with Branch screaming "the Bergens are coming!", Grandma, Chef and Creek.
