The actor for General Zaroff, Braxton Allgood, missed three days of production and had two different doubles to cover for the actor. With shots out of focus and insert shots on hands/shoulders, the magic is seamless.
The majority of the cast and crew for the film were between 16 - 28 years old.
For the boat and ocean scenes, the crew moved a parked speedboat into a parking lot to film the dialogue scenes. Once Rainsford (Rosencrantz) falls off the boat, the location switched from a bean bag in a parking lot to a swimming pool mimicking the ocean.
