Continuity mistake: Early in the film, when the gypsy Bela becomes a wolf that attacks Jenny and bites Talbot, he is in true four-legged animal form, sans clothing. After being killed, his human corpse is wearing clothes although it is remarked that his feet are bare. Later, when Talbot transforms, he is a Wolf-Man, wearing clothes and walking on two legs.
Question: At the time that this movie was made, nobody knew what made a werewolf, what could kill a werewolf, or when a werewolf would appear. Who decided that these things could happen?
