We all know that Robert DeNiro grew up to be Marlon Brando (in The Godfather 2 and The Godfather.
And it looks like Leonardo de Caprio grew up to be Jason Robards (The Aviator and Melvin and Howard
And, of course Cate Blanchett grew to become Bette Davis (Elizabeth and The Private Lives of Elizabeth and Esses).
And Errol Flynn grew up to be Sean Connery (The Adventures of Robin Hood and Robin and Marian).
Ground rules – must be in two different movies. Extra credit if the character is fictional.
