Trivia: Reportedly, Barbara and Adam from the original were going to have a cameo, but it was cut, as Tim Burton doesn't believe current digital de-aging technology is believable enough.
Trivia: When Delores is reassembling herself, you can see she is missing the ring finger of her left hand. If you recall, Beetlejuice had this same finger adorned with a ring in his pocket when he attempted to marry Lydia in the first film.
Trivia: One of the conditions Tim Burton and Michael Keaton set for directing and appearing in the film is that they would only make it if they could use practical effects in place of CGI as much as possible, just like the original. This is why the film makes heavy use of things like old-school stop-motion animation and animatronics... CGI was only used when necessary.
Trivia: Brad Pitt, who is a producer on the film, was reportedly going to have a cameo in the afterlife waiting room as a character who was shot in the head (possibly implied to be his character Chad from "Burn After Reading"), but it was cut for one reason or another.
Trivia: The way Delores is stapled back together makes her resemble Sally from The Nightmare Before Christmas.
Trivia: Michael Keaton said at Cinemacon 2024 that this was the most fun he ever had making a film.
Answer: Why are most people so intent on marrying someone? He loves Lydia. In the first movie, she was a teenager, and he mostly needed a wedding to get out of his punishment. In the years since, he appears to have developed more respect and appreciation for her. He stopped her wedding to Roy, exposed Roy's fraud, and transformed their almost-wedding into the smaller, "private" ceremony that she really wanted. He doesn't want to "just find someone else" for the same reasons that many people don't.
