The Nutty Professor. 1963. USA. Directed by Jerry Lewis. 107 min.
Screenplay by Lewis, Bill Richmond. With Lewis, Stella Stevens, Kathleen Freeman. Lewis’s growing fascination with multiplied selves and divided personalities led to his masterpiece, a lacerating, self-reflexive variation on Dr. Jekyll and Mr. Hyde. Socially inept chemistry professor Julius Kelp discovers a formula that transforms him into the oleaginous lounge singer Buddy Love, a rich metaphor that Lewis explores with insight and unflinching self-consciousness.
