An exceptional cast and intelligent direction seals the quality of the first 'talkie' version of Robert Louis Stevenson's tale. Often hailed as the best of the many screen adaptations of the story, director Robert Moumalin exploits the symbolic potential of the tale as well as boldly tapping into popular Freudian trends concerning sexual repression. The result is not a by-the-numbers rendition but an effective interpretation with quirks and dimensions of its own. Yet the film belongs to Frederic March who scooped an Oscar for his sensational dual role. Although as Jekyll he unfortunately has to trade flowery romantic dialogue with Rose Hobart, there can be no disputing the menace of his Hyde, with his simian-like appearance, top hat, cloak and cane, who turns cockney hooker Miriam Hopkins' life into a nightmare. It's a breathtaking transformation both physically (thanks to stellar make-up and special effects) and artistically and is undoubtedly the centrepiece of this excellent vintage classic.
