This film mostly consists 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 went to Hollywood, hired 12 girls from a Selma Avenue brothel and paid each one $10 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.
