This renowned thespian might be known for his many roles and British accent, but Caine’s early years could make for a film in itself. Growing up already impoverished in Southwark, London during World War II, Caine was sent to live with another family in Norfolk to escape the Blitz. But while at this new home, he and another boy were locked in a cupboard with nothing but water while their caretakers left for the weekend. Later in life, Caine served in the Korean War for two years before he returned home and continued acting.
