- Actor-Inspired Element: According to an interview with Jim Carrey, he says that the gag of Fletcher chasing his son as "The Claw" was something Carrey's father did to him and his siblings. He also came up with the idea for the closing scene. He woke Tom Shadyac up in the middle of the night to tell him about it.
- Cowboy BeBop at His Computer: Fletcher tells Max that he got tickets to a Professional Wrestling show that featured Rick Rude and Randy Savage in the main event. Not only were the two signed to different promotions at the time (WWF and WCW respectively), but Rude retired from in-ring work in 1994, three years before the film's release. Of course, it might be justified given Fletcher's character.
- Deleted Role: Randall 'Tex' Cobb, has a cameo in this movie talking about returning a jacket he had borrowed from Fletcher. He also had a whole character in the movie but the scene was later deleted.
- Deleted Scene: The deleted scene shows Fletcher in court, managing to convince an entire jury that a thug who robbed an old man and assaulted a female officer was the real victim in the whole fiasco. The scene was cut likely because the filmmakers feared it would make Fletcher too unlikable, though some have pointed out that we actually get to see how great of a lawyer he actually is, rather than just hear about it.
- Dyeing for Your Art: Fletcher kicking his own ass in the bathroom? That's Jim Carrey actually hurting himself.
- Fake American: British Cary Elwes as Jerry does a pretty convincing American accent.
- In Memoriam: The film was dedicated to Jason Bernard, who played Judge Marshall Stevens. Bernard died of a heart attack shortly after filming had finished.
- Missing Trailer Scene: One trailer included moments from a deleted opening scene in which Fletcher unscrupulously defends an obviously guilty Mr. Skull against a terrified old man in court.
- Uncredited Role: Judd Apatow was an uncredited script doctor for the screenplay.
