- Billing Displacement: The director himself actually lampshades this on the DVD Commentary, regarding Kenan Thompson's billing during the end titles as part of the main cast, despite his appearance being nothing more than a glorified cameo towards the end of the movie (and is joked that his spot during the end titles is just as long as his actual appearance in the movie itself was).
- The Cast Showoff: The film's plot is meant to accommodate Dana Carvey's trademarked ability for uncanny impersonations. One of the outtakes also includes a shot of Carvey, in his turtle suit, playing drums, alluding to Carvey's drumming abilities.
- Creator Killer: The Master of Disguise was the directorial debut of production designer Perry Andelin Blake. This film's nuclear failure with critics drowned his directing career immediately, with the nearest he's ever gotten to the director's chair in the years since being a few second unit director credits on other Happy Madison Productions films.
- The Danza: Jennifer Esposito as Jennifer Baker.
- Dawson Casting: Pistachio is supposed to be 25. Dana Carvey was 47 at time of filming.
- Executive Meddling: Executives insisted on not having Pistachio's grandfather be able to help Pistachio rescue his parents, so the joke/plot point of Pistachio's grandfather not being able to directly help because of family tradition was added into the film as a result.
- Old Shame: When asked by a fan on Twitter on how they should punish their kid for mispronouncing Data, Brent Spiner told them to make their kid watch this film. In fact, during the endless end credits, you can see Spiner do a pretty clear Aside Glance that screams, "Get me out of here."
- So My Kids Can Watch: Dana Carvey agreed to the film because his children were too young to watch any of his other movies, which were all decidedly family-unfriendly.
- Star-Derailing Role:
- This film was intended to get Dana Carvey out of the career slump that his failed sketch comedy show, The Dana Carvey Show, had started six years prior; it was also his first big role following his botched heart surgery and the lawsuit which followed. Instead, it obliterated what little of a career he had left. Since then, he's mainly stuck to standup with the occasional minor role in other poorly-received comedies like Jack and Jill and The Secret Life of Pets.
- Neither this film nor Star Trek: Nemesis did Brent Spiner's cinematic career any favors.
- Urban Legend of Zelda: The "Turtle Club scene was filmed on 9/11" story. For years, there was a story going around that the Turtle Club scene was being filmed as 9/11 happened, and there was a moment of silence with Dana Carvey in full Turtle Man costume. What actually occurred was the Turtle Club scene was delayed because of 9/11. Though when filming resumed on September 24th of that year, there was indeed a moment of silence with Carvey in full costume.
- What Could Have Been:
- An alternate ending had Pistachio taking Bowman down dressed as Captain America. The kids who appear in the scene are still acknowledged in the credits.
- Jim Carrey and Adam Sandler were considered for Pistachio Disguisey.
