This is by far the best of the Jerry Lewis (sans Martin) films. The Jekyll & Hyde storyline is the perfect outlet for Jerry Lewis' "physical comedy" genius. I bet the "French" were inspired by this performance, when they named Jerry Lewis their comedy idol. As a clumsy, yet lovable chemistry professor, the title character could hardly be considered a "babe magnet". When he discovers a magic potion that turns the nerd into "Buddy Love", his luck with the ladies appears to change. In the end, he learns that appearance is less important than character. A young Stella Stevens is effective as the grad-student love interest.
This original "Nutty Professor" is heartwarming and funny without offensive language and double-meaning visuals. It is far superior to its 1990s Eddie Murphy remake. Especially for a juvenile audience, Lewis beats Murphy by a mile!
