Dashing young doctor Jekyll is a raging success. He lectures at the medical college, lives in a mausoleum of a house with staff and plays a giant pipe organ proficiently. Add to this his betrothal to one of London's most eligible debutantes. Can it get any better? Well, yes. The fiance's father is resistant to give his permission and Jekyll is obsessed with experiments in the duality of human physiology, that of good and evil. But what could go wrong? Surely you know the story. I'm not that familiar with Frederic March's early filmography, but I'm inclined to believe this film is something of a cornerstone in his long career. He's good as Jekyll but he's superlative as Jekyll's alter ego Hyde. Some schmaltzy scenes and aged print detract, however the production is a tribute to the advancement of movies in 1931.
