In spite of almost universal criticism, this immensely accomplished comedy remains actor/co-writer/director Jerry Lewis's best and funniest screen work. It's really "Doctor Jerry and Mister Love" (the film's French title translated), as Lewis plays nerdish chemistry professor Julius Kelp who is hooked on lovely student Stella Stevens. Lewis makes and takes a potion that turns him into Buddy Love, singing lounge lizard par excellence. The witty design and the use of fabulously rich Paramount Technicolor are major bonuses, and this clever movie remains extremely funny.

A timid, nearsighted chemistry teacher discovers a magical potion that can transform him into a suave and handsome Romeo. The Jekyll and Hyde game works well enough until the concoction starts to wear off at the most embarrassing times.
