Michael Keaton’s name isn’t actually Michael Keaton.

The “Batman” star chose to use a different last name when he became famous.

Keaton landed roles in “Night Shift,” “Mr. Mom” ​​and “Beetlejuice” in the ’80s, before 1989’s “Batman” propelled him to superstardom.

“I was flipping through — I can’t remember if it was a phone book,” Keaton, now 72, said in an interview with People magazine. “I must have thought, ‘I don’t know, let me think of something.’ And I thought, ‘Oh, that sounds reasonable.'”

Keaton wanted to use the hybrid name for the credits of his latest directorial project, “Knox Goes Away,” but “forgot.”

“I said, ‘Hey, just as a heads up, my credit goes to Michael Keaton Douglas.’ And it completely slipped my mind,” he told the outlet. “And I forgot to give them enough time to put it in and create it. But that’s what’s going to happen.”

The actor has an upcoming project, “Goodrich,” that is in post-production.

It is not yet clear whether Keaton will use Michael Keaton Douglas for the credits.
