Jim Carrey gives the performance of his career as the insanely inventive comedian Andy Kaufman, best known as lovable mechanic Latka Gravas on the 1970s sitcom "Taxi," who shocked audiences with his caustic, off-the-wall routines. Director Milos Forman vividly recreates the era (with help from Lorne Michaels and David Letterman, who play themselves) and profiles a man who often blended comedy with performance art.
