Rain Man

Fast-talking yuppie Charlie Babbitt is forced to slow down when he meets a brother he never knew he had, an autistic savant named Raymond (Dustin Hoffman, in an Oscar-winning role) who's spent most of his life in an institution. When their wealthy father dies, leaving everything to Raymond, Charlie takes his unusually gifted older brother on a life-changing cross-country odyssey that neither is likely to forget.
