Michael Keaton's name isn't really Michael Keaton.
The "Batman" star chose to use a different last name as he became famous.
Keaton grabbed roles in "Night Shift," "Mr. Mom" and "Beetlejuice" in the 1980s before 1989's "Batman" pushed him into superstardom.
"I was looking through – I can’t remember if it was a phone book," Keaton, now 72, recalled in an interview with People magazine. "I must’ve gone, ‘I don’t know, let me think of something here.’ And I went, ‘Oh, that sounds reasonable.’"

The actor has an upcoming project, "Goodrich," which is in post-production.
It's unclear whether Keaton will use Michael Keaton Douglas for the credits.
