Actors Who Became The Character

What roles, in your opinion, were so convincing that the actor fully became the character? The first ones that come to mind for me are Robert Downey Jr as Iron Man, Johnny Depp as Captain Jack Sparrow, and Val Kilmer as Doc Holliday.I could NEVER see any other actor playing those roles, ever. What other performances fit this category? via /r/movies https://ift.tt/3ueI60o
