Michael Keaton Already Reprised 'Beetlejuice,' You Just Didn't See It

Unless you were in his house. In which case, that's... pretty weird.

More than 25 years have passed since Michael Keaton's "Beetlejuice" hit the big screen, but it hasn't been that long since he's slipped into the ghoul's zebra-striped suit.

During an appearance on the Happy Sad Confused podcast, the "Birdman" Golden Globe winner admitted to host Josh Horowitz that he's paraded around his house trying out his Beetlejuice shtick from time to time, just to make sure he still has the ghost with the most within him.

"I just said, 'How do I know?'" Keaton said, about one day deciding to explore if he still has the "Beetlejuice" juice. "I got caught doing some really ridiculous things in the house."

Keaton's private moments as the paranormal prankster might not be so private for much longer, if things go according to plan. Both Keaton and director Tim Burton have announced their intentions to make a new "Beetlejuice" movie, which is a daunting prospect even by Keaton's standards.

"We're running the risk of walking over sacred territory," he said. "It's like sacred Indian burial grounds — you never ride across that."

But Keaton's willing to make the ride, assuming he and Burton and others can arrive at the right ideas. And one of those ideas, according to the actor, is to keep Beetlejuice's presence pretty limited. Keaton said that the title character isn't actually seen on-screen more than a handful of minutes in the original "Beetlejuice," and the sequel shouldn't stray from that idea.

"I think it would be a huge mistake if we increase the [screen time] by much," he said. "But I'm wide open. Somebody might come along with a concept that is so vastly different [from mine]. I don't know."
