Prior to the Monsters HD channel airing of the film and the subsequent DVD and Blu-ray releases, the home media releases before 2007 contained the censored R-rated cut which removed the following:
- Katherine being molested a few seconds longer by Pretorius.
- Dr. Bloch taking 14 seconds longer attempting to remove the pineal gland hump from Crawford's forehead.
- A longer scene of Crawford eating the brains in the morgue.
- Additional footage of Crawford sucking out Dr. Bloch's eye and spitting it out onto the floor before then sucking at her socket.
- The ambulance driver's death by three blows to the head instead of just one.
- A brief shot of blood graphically spurting as Katherine bites off Crawford's pineal hump.
