Trivia: In the Ink and Paint Club, when Jessica is about to do her number, just as the curtains open, her dress snaps off for a split second, then reappears. This can only be seen in slow motion on the laserdisc version, however.
Trivia: Ever wonder what all that technical jargon that Judge Doom rattles off about his "Dip" was all about? The Dip, which he tells Eddie is a mixture he has made out of acetone, benzene, and turpentine, is the only way to kill a toon. Why? Because these are essentially the three main ingredients in "Paint Thinner" - which he uses to literally remove a toon's paint, thereby removing their existence.
Trivia: When the filmmakers sought permission to use the Looney Tunes characters in the film, Warner Brothers only agreed on the condition that Bugs Bunny receive equal screen time with Mickey Mouse.
Trivia: Another scene of Jessica's exposure can be found when Benny the cab crashes into the lamp-post after sliding through the puddle of dip. She and Eddie are thrown from the car, and spin around. As Jessica spins, she is seen to have no panties on. This is only visible on the original VHS and Laserdisc versions. On the DVD, fabric from her dress has been added to cover the exposure.
Trivia: In early versions of the script, Judge Doom had a pet vulture and was the one who shot Bambi's mother.
Trivia: After filming, Bob Hoskins had hallucinations, and his son became angry at him for not bringing any of his cartoon friends home.
Trivia: In a bit of irony, Bob Hoskin's live-action character Eddie Valiant had to be animated in a few quick shots during the car-chase with the weasels and Bennie the cab, due to the high-speeds and/or chaotic movement, which would have been too dangerous (or too impractical) to do with Bob Hoskins or a stunt-double. These shots (which actually look fairly creepy, due to Valiant's animated form falling into "uncanny valley") are most easily seen by going frame-by-frame in certain quick shots.
