Trivia: The legs of the magician's assistant character (the lady who is cut in half) were "played" by Tim Burton's then-girlfriend.
Trivia: The original script was significantly different from the final film. For example, Beetlejuice himself was initially envisioned as a murderous winged demon who would occasionally take on the form of a short, portly middle-eastern man. And the humor and content was meant to be much darker. The originally climax had the Maitlands trying to save Lydia from being raped by Beetlejuice's true demonic form, as opposed to marrying her as seen in the final film. Tim Burton liked the idea behind the film, but pushed for it to be made more light-hearted and less graphic, and it was subsequently re-written into the film we know today.
Trivia: While the film is called "Beetlejuice," the character's name in the film is actually spelled "Betelgeuse." It was decided to re-spell the name in the trailers and on the film's title card for marketing purposes, to make it easier for audiences to be able to pronounce the name.
Trivia: Catherine O'Hara met her future husband, production designer Bo Welch, while making this film.
Trivia: In a deleted scene, which can be found on YouTube, Charles and Delia are shown living or staying in New York again. Lydia stays at the house in Winter River, finishing school and being watched over by Adam and Barbara. Presumably this ending was changed because the Winter River locals would question Lydia living "alone", as her involvement with the ghosts is a secret.
Chosen answer: Barbara did conjure him earlier in the movie when she saw lights in the model going off and then said his name three times. According to Juno, they let Beetlejuice out but didn't put him back, which gave him the opportunity to attack the Deetzs.
