Nerd. Milquetoast. Klutz. These are just three of the many undesirable words that can be used to describe Professor Julius Kelp. But all that changes when the chemistry expert invents a potion that transforms him into a suave, sexy chick magnet, whom Julius aptly names Buddy Love. Unfortunately, there's one side effect: Buddy can't control when he'll change back into Julius, an event that always happens at inopportune times. How will Julius/Buddy resolve his Jekyll-and-Hyde dilemma' This film cemented Jerry Lewis's reputation as a comic genius; he co-wrote and co-produced the film while also turning in a fabulous performance. This film served as the basis for Eddie Murphy's later Nutty Professor films.
