Rouben Mamoulian's still-stunning 1931 Paramount version of Robert Louis Stevenson's classic story opens in POV and delivers innovations in make-up and effects throughout. It also features an unforgettable turn from Fredric March, his Oscar-winning Jekyll a charitable doctor who plays God to assuage his bubbling carnal frustrations... And turns sinister and simian as Hyde.
It's a lot better than Victor Fleming's 1941 remake, with Spencer Tracy's unlikeable Jekyll merely dishevelling his hair to unleash the beast within. More melodrama than horror, it lacks the style or subversive humour of Mamoulian's benchmark movie.
