It's no secret that a Beetlejuice sequel has been in the works for some time now, with a script by Seth Grahame-Smith (who wrote Tim Burton's Dark Shadows, as well as Abraham Lincoln: Vampire Hunter). Last year, when we spoke to Grahame-Smith at the Dark Shadows junket, he told us that he and Burton were "talking about the possibilities" of a Beetlejuice sequel. According to Hollywood Reporter, Warner Bros. has a script by Grahame-Smith and David Katzenberger (whose only other writing credit is on MTV's The Hard Life of RJ Berger) and has officially extended the offer to direct to Burton.
Burton, of course, is the mastermind behind the original Beetlejuice in 1988, and Warner Bros. has a long history with Burton, so it seems natural that the offer would go out to Burton. Now it is just a matter of whether or not Burton will say yes. He is currently wrapping up on Big Eyes, a biopic about artist Margaret Keane and the legal battles she had when her ex-husband tried to take credit for her iconic paintings of children with ridiculously big eyes. Next up for Burton is Miss Peregrine's Home for Peculiar Children, based on the book, which is slated to start in 2015. So if Burton returns to the underworld, it probably wouldn't happen until 2016.
Personally, I can't imagine Beetlejuice without Burton.
