Werewolf of London

Werewolf of London is a 1935 horror film directed by Stuart Walker and starring Henry Hull as the titular werewolf. The supporting cast includes Warner Oland, Valerie Hobson, Lester Matthews, and Spring Byington. Jack Pierce, who is best known for creating the iconic makeup worn by Boris Karloff in the 1931 film Frankenstein, created the film's werewolf makeup. Produced by Universal Pictures, Werewolf of London was the first feature-length werewolf film. Plot Wilfred Glendon, a wealthy and world-renowned English botanist, journeys to Tibet in search of the extremely rare plant Mariphasa lupina lumina, which is rumored to be nourished by the moon. While there, he is attacked and bitten by a feral humanoid creature, but he succeeds in acquiring a specimen of Mariphasa. He constructs a lamp that simulates moonlight in his London laboratory and waits for the plant to bloom. At a party, Wilfred is approached by a fellow botanist, Dr. Yogami, who claims they met, briefly, in Tibet, where he also was seeking the Mariphasa. Yogami tells Glendon the plant is a temporary antidote for "werewolfery" (or "lycanthrophobia"), and responds to Wilfred's skepticism by claiming he knows of two men in London who are werewolves, having been bitten by another werewolf. Eventually, one flower of the Mariphasa opens under Wilfred's moon lamp. When his hand grows fur in the artificial moonlight, he cuts the blossom and dabs its sap at the fur, and he is amazed to see the transformation reverse. Yogami visits, asking for two blossoms, as that night is the first of four nights around the full moon when the werewolves he mentioned will turn if left untreated, but Wilfred refuses. Before he goes, Yogami cautions that werewolves try to kill whatever they love best.
