Zelig

Leonard Zelig (Woody Allen) is a social quick-change artist whose neurotic insecurity forces him to mimic whomever he's with. Treated by Dr. Eudora Fletcher (Mia Farrow), Zelig is cured and, in the process, goes from side-show freak to celebrity to Eudora's fiancé! But when misdeeds from Zelig's multiple personality past start to surface, the human chameleon is on the run again, and Eudora must search the world over to find and save the only man who's every man she's ever wanted!
