The Nutty Professor is a 1963 American science fiction comedy film directed, co-written by, and starring Jerry Lewis. The film also co-stars Stella Stevens, Del Moore, Kathleen Freeman, Howard Morris, and Elvia Allman. The score was composed by Walter Scharf. A parody of Robert Louis Stevenson's 1886 novella Strange Case of Dr. Jekyll and Mr. Hyde, it follows weak-willed scientist Julius Kelp as he creates a serum that transforms him into a charismatic but narcissistic ladies' man called Buddy Love.
