The music in the film appears to borrow heavily from Dominic Frontiere's score for the 1963-1965 TV series "The Outer Limits".
The film is also known as The Possession of Nurse Sherri, Black Voodoo, Beyond the Living, Hospital of Terror, Killer's Curse, and Hands of Death.
In 2017, the film was restored in 2K and released on DVD and Blu-ray by Vinegar Syndrome.
The opening scenes in the film that are set in the desert were added in a re-shooting of it.
The bulk of this film was shot in California; however, several pick-up shots were filmed on the East Coast of the U.S.
