Fun list from New York Magazine's Vulture: Best multiple-role performances. Agree about Alec Guinness in Kind Hearts and Coronets, Peter Sellers in Dr. Strangelove, Eddie Murphy in Bowfinger, Jeremy Irons in Dead Ringers and Nic Cage in Adaptation. But the Vulture forgot the "Eve" movies: Barbara Stanwyck in The Lady Eve and Joanne Woodward in The Three Faces of Eve. And failed to mention Olivia de Havilland  and Bette Davis in the ultimate "there's two of them!" twin films, A Stolen Life and The Dark Mirror. And neglected Hayley Mills and Lindsay Lohan in The Parent Trap movies.

I love seeing an actor compete against him or herself, don't you? In the twinfilms, it's fun to watch the actor playing the bad twin pretending to be the good twin. Which films have we missed?
