 This film consists mostly of previously shot footage. To spice  things up, the producers decided to shoot additional material that  showed bare breasted "natives" being menaced by a gorilla. Marshal  Gordon borrowed twelve girls from a Selma Avenue brothel, and paid  each of them ten dollars in advance. When fog rolled in onto the  location and temperatures dropped, the actresses demanded additional  pay. The projected budget of $8,500 increased to $11,000 by the end  of the day, when shooting of the scene finally wrapped.
