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: Near the end of the film, as Dani is lifted and being carried to the dinner table, if you look closely, you can see the ghostly image of her deceased sister's face (with the exhaust hose in her mouth) in the background. It's been superimposed over the trees in the distance. It's very subtle and easy to miss, but if you know where to look, it's there.
Trivia: If you look closely in one of the shots looking at the musician's pad you can see Hitchcock making a cameo like he does in all his movies. If you pay attention however, you might notice that this is a reenactment of a scene from one of his other movies, 'Rope.' Also, Hitchcock is standing in for James Stewart and the character he played in 'Rope' since Mr. Stewart is busy spying on this scene. (00:26:15)
Trivia: Numerous references to other Tim Burton films: a) The dress Katrina Anne Van Tassel wears at the end is similar to Beetlejuice's outfit. b) Crane has various sharp scissor-like tools, which is a reference to Johnny Depp's early film "Edward Scissorhands" (1989). c) The scarecrow at the beginning looks exactly like Jack from "The Nightmare Before Christmas" (1994). d) The covered bridge is a lot like the bridge in "Beetlejuice."
Trivia: In the scene where Lenny is on the phone describing how Sammy Jenkis ends up in a home due to the death of his wife, it shows Sammy sitting in a chair looking towards the camera. Sammy is temporarily blocked from our view by someone walking in front of him. As the person passes by, it is not Sammy that re-appears, but Lenny. To see it well, you will have to use the frame-by-frame mode. There are about 5 visible frames of Lenny in the home, and then it cuts back to him inside the motel room talking on the phone again.
