Although James Cruze was credited as playing both Dr. Jekyll and Mr. Hyde, in some scenes Hyde was actually played by Harry Benham. In a 1963 interview published in Famous Monsters of Filmland magazine, Benham remembered that he and James Cruze shared the same costume and wig, but had their own separate sets of false fangs.
One of the few film adaptations of the novel by Robert Louis Stevenson that features a "dwarfish" Mr. Hyde, as in Stevenson's novel.
