Spencer Tracy and Ingrid Bergman headline this screen version of Robert Louis Stevenson's tale, directed by Gone with the Wind and Wizard of Oz legend Victor Fleming. Tracy stars as Dr. Jekyll, a scientist who downs an experimental elixir that transforms him into a monstrous alter-ego, Mr. Hyde. Lana Turner co-stars as Jekyll's fiancée, and Bergman as Eva, the woman who captures his heart. A film steeped in heavy Freudian symbolism, this production also tries something unusual by relying largely on Tracy's shift in facial mannerisms (in lieu of heavy make-up) to convey the personality change. As a result, the movie manages to place a much stronger emphasis on emotions than on the terror of physical mutation.
