A psychological horror drama, Dr. Jekyll and Mr. Hyde is a remake of the 1931 Oscar-winning version, this time starring Spencer Tracy as the dual title characters. The film follows the same course of action as its predecessor, with Tracy playing the scientist who creates a potion that unleashes his darker alter ego. When Dr. Henry Jekyll's evil side, Mr. Hyde, takes over, he wreaks havoc on those around him, leading to tragic consequences for himself and those he loves.
