Robert Downey Jr. – Tony Stark/Iron Man

Robert Downey Jr.’s private life has never been much of a secret. He has struggled with substance abuse in the past but has managed to turn his life around. He draws many parallels both in personality and physical resemblance to billionaire, genius philanthropist and playboy Tony Stark in the Iron Man movies. Robert, much like his character Tony, both have fallen down, only to get back and stand taller than ever before.
