The same Universal Studios makeup artist, Jack P. Pierce, designed the makeup for both Wilfred Glendon, the werewolf in this movie, and for Larry Talbot (Lon Chaney Jr.), the wolf man in The Wolf Man (1941), although Hull chose to wear a less hairy version because he disliked the time it took to cover his face in all that wolf hair. They both became werewolves when they were bitten by another werewolf, Glendon by Dr Yogami and Talbot by the gypsy Bela (Bela Lugosi). This werewolf strain, however, seems to have some differences from the one Larry Talbot contracted. For example, Talbot couldn't escape from becoming a werewolf on the nights of the full moon, but in Werewolf of London, the juice from the Mariphasa lupina lumina is an antidote against "lycanthrophobia" (werewolfery) if it is taken on the nights of the full moon. Talbot's affliction was permanent (and lasted through six more sequels), whereas the werewolf legend in this movie says that the use of the Wolf Flower, although it is not a cure, can prevent the affliction from becoming permanent. Another difference is that, In The Wolf Man, Talbot chose his victims indiscriminately, however, werewolves in London instinctively seek to kill the ones they love best. Finally, Wilfred Glendon is killed by a bullet, whereas Larry Talbot requires a silver bullet shot by someone who loves him.
