Actor Michael Caine, 83, has officially changed his name.

To "Michael Caine."

Until now, his legal name was "Maurice Micklewhite."

"I changed my name when all the stuff started with ISIS," the artist formerly known as Micklewhite told The Sun. "An airport security guard would say 'Hi Michael Caine,' and suddenly I'd give him a passport with a different name on it. I could stand there for an hour. So I changed my name."

Michael Caine is his second stage name. He started out as "Michael Scott" in theaters in Sussex. He changed it when he moved to London and there was already another theater actor with that name.

He picked up Michael Caine in 1954, taking it from a billboard in Leicester Square for the Humphrey Bogart movie "The Caine Mutiny." Two years later, he'd have his first credited movie role and has been known as Michael Caine in the 60 years since then.
