Wood persuaded Lugosi, at the time poor and drug-addicted, to appear in the movie. Lugosi's scenes were shot at the Jack Miles Studios in Los Angeles. He was reportedly paid $5000 for the role, although some stories state the actual amount was only $1000. Lugosi is credited as "The Scientist", a character whose purpose is unclear. He acts as a sort of narrator but gives no narration relevant to the plot; that job is reserved for the film's primary narrator, Timothy Farrell.
