Eddie Murphy - The Nutty Professor and Coming to America

Martin Lawrence- Big Momma's House I and II

Mike Meyers - Austin Powers and Dr. Evil

Eddie Murphy has done it several times starting with "Coming To America." Most notably in "The Nutty Professor," "The Klumps: The Nutty Professor II" and "Norbert."

John Rhys-Davies performed both Glimi and Treebeard the Ent in "Lord Of The Rings: The Two Towers."

Kenneth Branagh & Emma Thompson played reincarnated lovers in "Dead Again." You had Branagh playing a composer and a private eye with Thompson playing the composer's wife and the amnesia sufferer the private is trying to help.

Then there are all those actors who played "The Man In The Iron Mask" and the two male leads in "A Tale Of Two Cities."

Jose Ferrer played Henri de Toulouse-Lautrec and his father The Comte de Toulouse-Lautrec in the original "Moulin Rouge" (1952)
