Born Maurice Micklewhite on March 14, 1933, Michael Caine grew up in south London. It wasn't long before the young actor decided he needed a stage name, and he took his new last name from the Humphrey Bogart classic The Caine Mutiny.

In 2000, Queen Elizabeth granted Caine a knighthood under his real name. He chose to use his birth name in tribute to his father.
