Jerry Lewis directed, co-wrote and starred in this riotously funny movie that set a new standard for screen comedy. With Stella Stevens. Madcap maestro Jerry Lewis wrote, produced, directed and starred in this frantic, far-out take on the Jekyll and Hyde tale. He plays Dr Julius Kelp, the nerdy chemistry professor who invents a potion that turns him into an ultra-cool ladies\' man, Buddy Love. In order to help him get close to his favourite student Stella Purdy and to overcome the humiliation that\'s been heaped on him all his life, Julius invents a special formula intended to transform him from a shy, timid academic into a handsome casanova. The experiment works well, turning Julius into the incorrigible Buddy Love and giving him the courage to approach his beloved Stella, but it is a transformation which tends to wear off at the most unexpected moments....
