63. ALEC GUINNESS
Kind Hearts and Coronets (1950)

Throughout his career, Sir Alec epitomized the actor as chameleon, seemingly morphing from movie to movie. But in this deceptively genteel comedy, he performs the feat repeatedly, playing eight members of a haughty aristocratic clan, all deliciously doomed to be murdered. From the doddering bank president to the old-maid suffragette, each is a distinctively silly caricature. Together, they're a virtuosic tour de force.
