Michael Keaton s going back to his roots.

The Beetlejuice Beetlejuice actor recently told People he plans to revert to a version of his birth name, Michael Douglas, for future projects.

When he was starting out in his career in the 70s, he chose a stage name because of a Screen Actors Guild rule that prohibits members from using the same professional name as another member.

The SAG already had a Michael Douglas the Oscar-winning Wall Street actor and a Mike Douglas, so Keaton had to get creative.

I was looking through I cant remember if it was a phone book, he told People. I mustve gone, I dont know, let me think of something here. And I went, Oh, that sounds reasonable.
