Seth Meyers, another Saturday Night Live (1975) alumnus, stopped by the set one day and came up with the "too legit to quit" scene.

During the filming of the opening scene, where Rod attempts jumping over the bus, the stuntman playing Rod actually broke his leg.

The band called "Gown", that plays at Rod's final jump, is actually Queens of the Stone Age.

Rod tumbles down the hill for forty-seven seconds.

Bill Hader's long hair in the movie was not a wig. Instead, he had hair extensions put in, which he wore through the entire summer the movie was shot.

Rod sings that he does his laundry without pants, and is in his underwear. He then walks into a room, wearing pants. This blooper was intentional, and was planned by Director Akiva Schaffer.

All of Andy Samberg's (Rod's) stunt doubles had prosthetic noses, to make them seem as big as Andy's. Jorma Taccone (Kevin) and Akiva Schaffer played a joke on Samberg, by requesting the prosthetics be larger than his own nose, so he would feel insecure.

Although Pam Brady is credited as the writer of the film, The Lonely Island (Andy Samberg, Akiva Schaffer, and Jorma Taccone) re-wrote the entire script to suit their style.

The scene where Rod (Samberg) asks Cathy (Britt Irvin) out and starts laughing hysterically was improvised by Andy Samberg.

Even though Andy Samberg plays the older brother of Jorma Taccone, Taccone is actually the older one in real-life.

Originally intended as a vehicle for Will Ferrell. He received an Executive Producer credit. The Lonely Island re-wrote the script, because it couldn't be read without Ferrell in mind, and Schaffer didn't want the movie to be an impression of Ferrell.

Jorma Taccone, Andy Samberg, and Akiva Schaffer made this movie between the 2005-07 seasons of Saturday Night Live (1975). The team started re-writing Pam Brady's script in June 2006. Filming began on July 24th and wrapped on September 23rd. The team reported back to SNL on September 25th.

During Rod's big jump at the stadium, Andy Samberg's real-life mother and father can be seen in the crowd.

The "Cool Beans" song was originally pulled by Akiva Schaffer, but the scene was edited by Samberg and Taccone, and eventually Schaffer reinserted the scene in the last test screening, where it received high remarks from the audience, with some saying it was one of their favorite parts of the film.

Shares the same basic plot line as Dirty Work (1998), which also starred then-current cast members of Saturday Night Live (1975). Both films are centered around an unsuccessful young man attempting to raise fifty thousand dollars for his father, a cranky ex-boxer, to have a heart transplant.

The scene involving Rod (Andy Samberg) ringing the bell over the pool, followed by the other guys singing along to the bell was completely improvised.

Almost every time Rico (Danny McBride) is holding a beer, it's real beer.

All of the pictures in the dining room of the Kimble and Powell house, are real childhood pictures of Andy Samberg and Jorma Taccone.

The scene where Rod jumps over the fifteen school buses featured over twelve hundred extras.

During the double date scene, Jonathan (Will Arnett) offhandedly refers to Rod as "Super Dave". This is a nod to "Super Dave" Osborne, a comedy stuntman played by Bob Einstein since the mid-1980s.

Behind the scenes, or after filming was done for the day, Jorma Taccone (Kevin) would often go naked from the waist down, (besides shoes and socks).

Feature directing debut of Akiva Schaffer.

Samberg had his own stunt double, but performed many of his own stunts as he was allowed to, like the pool jump.

During filming the scene with Denise ("You look pretty" "What did you say?" "Uh, I said you look s****y. Goodnight, Denise!") it was raining during the shots of Andy Samberg, and the rain had to be digitally removed.

Prior to the film's release, The Lonely Island (comprised of Samberg, Taccone, and Schaffer) promoted the film with interstitials during Comedy Central movie marathons. In the promos, the trio attempted to convince viewers that Hot Rod was the story of a sex-offender, "he does stunts to raise money to sex-offend."

Brittany Tiplady, who plays Maggie, Dave's (Bill Hader's) sister, had about a week left before she got her braces off, and she was excited to remove them in time for the movie, but Akiva Schaffer jokingly made her film her scene before she got her braces off.

Bill Hader (Dave) based his character off of his friend, Eric, and the "Tripping Balls" scene was based off of true events involving Hader and his friend, but in this case, Hader was Rod.

Akiva Schaffer's mother makes a cameo as an extra in two scenes. She's pelted with flyers by Richardson as she walks to her van, and later, she is shown sitting next to him during the screening of Rod's video.

In the commentary, the guys say they heard of John Farnham, because he had some songs in Rad (1986). They used the song "You're the Voice" by Farnham in the riot scene. Rad (1986) was a movie about a young man's journey to win a BMX race called Helltrack.

The gag in which the syllable WH was enunciated was inspired by a skit from the album "Moment of Truth" by the hip-hop group Gang Starr (Guru & DJ Premier).

Will Arnett (Jonathan) was only on-set for two days, so in the first scene, when he drives up in his car, it is not Arnett.

In the scene with Rod (Samberg) riding his bike to his date with Cathy (Britt Irvin) and singing "Ohhh when you're going on a date, and you put on a shirt! And you ride your bike to the daaaaate," was improvised by Andy Samberg.

Filmed in Vancouver, British Columbia.

The scene with Rod wearing bubble wrap and pillows and getting hit by the van, was inspired by the documentary "Grizzly Man."

The scene (introducing "Operation Fiscal Jackhammer") was filmed in the first day of shooting.

There are a few subtle references to professional wrestling in the movie, including two of the characters wearing WWE t-shirts. In one scene, Rod wears a Hulk Hogan "Hulkamania" t-shirt, and in another, Dave wears a "Stone Cold" Steve Austin t-shirt.

The scene with Denise (Isla Fisher) ripping tickets was the last scene filmed.

The original movie poster was a picture of Andy Samberg standing on a hilltop and taking a bow in front of his moped, much similar to the after-credits sequence. This poster was preferred by Akiva Schaffer, Adam Samberg, and Jorma Taccone. The studio wanted the movie's official poster to be the one featuring the main characters.
