Trivia: When the taxi Jessica and Eddie are in hits the lamppost, she spins around and her dress shifts position. For a couple of frames on the laserdisc version her underwear vanishes, or at least it appears to. Opinion is divided as to whether it's a deliberate move by the animators or just an error in colouring. (https://www.snopes.com/fact-check/who-stripped-jessica-rabbit/). (00:18:15)
Trivia: There is a trailer to this movie with an additional gag. After Ludwig has demonstrated his image of an ideal assassin to Papshmir, he sits down with the revolver used in the demonstration which had turned out to be empty. In the trailer shot (in a closeup of Montalban) the gun unexpectantly goes off.
