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."
