Miriam Hopkins ... Ivy Pierson
Rose Hobart ... Muriel Carew
Holmes Herbert ... Dr. Lanyon
Robert Louis Stevenson's classic tale of split personality has been filmed before in 1920 with John Barrymore and in 1941 with Spencer Tracy, but Rouben Mamoulian's expressionist 1931 version stands head and shoulders above the rest. First of all, you have Fredric March, whose tour-de-force performance as the good-natured Jekyll and the monstrous Hyde earned him the Best Actor Oscar. Second, the camera work by Karl Struss brilliantly captures the mood of the story. And lastly, the transformation sequences set an enormous precedent for the later monster movies. It all blends together to form one of most amazing horror movies of the 1930's. Even today, it still has the power to mesmerize and send chills down the spine of even the most hardened horror fan.
