Werewolf of London is a 1935 Horror film starring Henry Hull and produced by Universal Pictures. Jack Pierce's eerie werewolf make-up was simpler than his version six years later for Lon Chaney, Jr., in The Wolf Man. Werewolf of London was the first Hollywood mainstream werewolf movie. Wilfred Glendon (Henry Hull) is a wealthy and world-renowned English botanist who journeys to Tibet in search of the elusive mariphasa plant. While there, he is attacked and bitten by a creature later revealed to be a werewolf, although he succeeds in acquiring a specimen of the mariphasa. Once back home in London he is approached by a fellow botanist, Dr. Yogami (Warner Oland), who claims to have met him in Tibet while also seeking the mariphasa. Yogami warns Glendon that the bite of a werewolf would cause him to become a werewolf as well, adding that the mariphasa is a temporary antidote for the disease.
