There have been at least ten film adaptations of the novel, and at least four versions are available in video format through stores and libraries. The most critically successful film adaptation was the 1931 Paramount version directed by Rouben Mamoulian; but Lon Chaney’s performance in the 1920 version included phenomenal transformation scenes with no use of heavy make-up or appliances.
Since Stevenson’s copyright expired, dozens of variations on the story have been written as short stories, novels, made-for-television films, feature films, and episodes of television series. There is no way of cataloguing them all. Generally, these can be summed up as successful only in so far as they are derivative.
