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: When the film was released, Axl Rose told the crowd at Hilton Coliseum, Ames, IA, on 27th July 1988, not to waste their money and see "The Dead Pool," despite being in the film. Confirmable by listening to the show.
Trivia: When Colors was first screened in a university theater, a young film student was of the opinion that the studio who financed this film 'had no right to make a movie about a culture they knew nothing about', and that they were marketing it as a picture about black gangs when it was actually a film about 'two white cops.' This student eventually graduated, wrote a film, and directed it. That film was Boyz in Da Hood, and the writer-director was John Singleton, who at the time had had it with those 'stupid New Jack Shitty exploitation films about blacks.'
Trivia: There were palm trees near the Popes' home in FL and there were palm trees when they stopped at a motel in SC. Palm trees are expected in tropical and subtropical climates, but certain species can grow anywhere in SC under the right conditions. (This is true to a lesser extent in the warmer zones of North Carolina.) The "Sabal Palm" (A.K.A. "Cabbage Palmetto") is actually South Carolina's State Tree. The palms at the motel looked like "True Date" palms to me but were more than likely "Sabals." (00:02:44 - 00:08:12)
Trivia: The film's original title was "Red Rain" and the Peter Gabriel song of the same name was meant to be featured in the film. However, they couldn't get the rights to feature the song, so the song "Red Harvest" was commissioned and written specifically for the film. Shortly before the film's release, the studio decided that the title "Red Rain" no longer made any sense without the Gabriel song in the movie, and instead retitled the film "Jack's Back."
Trivia: The taxi driver who hands over the matches to Harrison Ford is the film's director, Roman Polanski.
