Tim Burton has said that this film would only be made if Michael Keaton would return to reprise his role. Keaton said in March of 2014 that this is the only sequel he's interested in doing.
Michael Keaton said he and Tim Burton were particularly interested in doing a film that wasn't too technology-heavy. They wanted it to have the same practical effects of the original.
Tim Burton stated he was done making movies until he directed the first four episodes of Netflix hit Wednesday (2022), which prompted him to reassess the original Beetlejuice and its potential for a sequel.
Winona Ryder had only one condition when she first met Stranger Things (2016) creators Matt and Ross Duffer for a role they wanted her to play on Netflix: If "Beetlejuice 2" ever got off the ground, they'd have to let her take a break from the series to film it. They agreed.
While seated next to the crazy cat lady in the waiting room, Beetlejuice comments, "I'm more of a dog person." Later, during his musical wedding number, his dog is shown as one of his past loves, along with Lydia and Delores.
