Trivia: Sonic makes a brief joke about the feud between the actors Vin Diesel and Dwayne Johnson, who both appeared in the "Fast and Furious" movie franchise. This film is from the same producers as that franchise.
Trivia: When Nancy Tremaine (Idina Menzel) is singing to Morgan about her memories to make the tree come to life again she sings a line "Let it glow, let it glow." This is an homage to Idina Menzel as Elsa in Frozen singing "Let it Go".
Trivia: Miles Bron's dining room features several paintings, from the most famous painting in the world the Mona Lisa to others, sometimes with garish self-insertions of Miles himself. One of the paintings is Mark Rothko's Number 207 (Red over Dark Blue on Dark Gray), which Rian Johnson explicitly asked to hang upside down - a hint to the fact that Miles is kinda clueless.

Trivia: Sweet Pete's tragic backstory is similar to Bobby Driscoll who voiced Peter Pan in the original Disney film. Many people have expressed disgust over this, as it distastefully satirizes Driscoll's own personal tragedy and downfall of being unable to find work after getting older.
Trivia: Before this sequel was confirmed, a made-for-TV remake of the original was almost produced for cable channel Freeform as announced in 2017. Star Bette Midler hated the idea of a remake, and openly stated her disapproval. Eventually, about a year later, talk of a proper sequel started up again and the made-for-TV remake was quietly cancelled.
Trivia: The first film Colin Farrell's pet donkey "Jenny" has appeared in, making her a "diva", according to Farrell. Her real name is also Jenny - the name was kept to help her react to commands. She kicked Colin Farrell at one point when he was trying to feed her.
Trivia: Sergei from Secret Life of Pets 2 can be seen in the bank.
Trivia: Series co-star Bam Margera was fired during production for reportedly failing to take cooperate with various conditions set for his appearance, such as random drug tests. After being fired, he started a lawsuit against the other creators and reportedly sent death-threats to longtime "Jackass" director Jeff Tremaine, resulting in Tremaine taking out a restraining order against him. Despite his firing, Margera did film a few scenes and does briefly appear in the finished film.

Trivia: Adam Nee, the co-director and co-screenwriter, has a cameo as Officer Sawyer.
Trivia: The original script was very different, and much more downbeat. It would have focused on Randal spiraling into depression after Hurricane Sandy destroyed the Quick Stop and much of the town. A sort-of shantytown village is started in the parking lot of a movie theater by displaced locals, where Randall would make a new makeshift Quick Stop. Smith described it as a movie about dealing with grief. Kevin Smith ended up re-writing it into a more hopeful, upbeat film a few years later.
Trivia: When Marlon Wayans is attacking the killer clown dragging the axe in the school, he says "homie don't play that." That is his brother Damon Wayan's famous tag line where he dressed as a clown in the series In Living Color. (00:39:27)
Suggested correction: Marlon Wayans didn't portray Homey The Clown in Living Color. Homey The Clown was played by his brother Damon Wayans.
Trivia: The animated sequences were actually filmed in live-action with the actors on-set, and then rotoscoped with 2D animation. Director James Gunn wanted to emulate the films of Ralph Bakshi, which often employed similar techniques of live-action footage being rotoscoped with animation.
Trivia: The film is inspired by the classic Mel Brooks comedy "Blazing Saddles," and is intended to be a child-friendly retelling, with many near-identical sequences. In fact, it was originally titled "Blazing Samurai," and it would have been about an African-American man becoming a samurai. It was eventually retitled, and the studio decided to rework the narrative by making it about a dog living in a world of cats, in order to make the anti-racism message more subtle and "universal."
Trivia: Chris Parnell is only 13 years older than his on-screen daughter, Rebel Wilson.
Trivia: After chasing the neighbor girl Nia from her hot cocoa stand, Karen said, "And your little dog, too" - equating Karen to the Wicked Witch in "The Wizard of Oz" who said the same to Dorothy regarding Toto. (00:02:15)
Trivia: The voice of the Tin Can Man was provided by Butch Patrick. Butch Patrick played the role of Eddie Munster, the son of Lily and Herman in the 1964 TV show "The Munsters".
Trivia: Was pulled from TIFF after a single showing because director/co-writer/star Vera Drew got a warning letter from an "unnamed" massive media conglomerate. (Widely believed to be Warner Bros./Discovery.) Eventually the movie was able to be released legally because, as a parody, its content falls squarely under fair-use laws.
