 Principal filming was done at Bronson Canyon, which was also used in  filming many movies to which Cadavra paid homage (the site permit  was the single largest expense in the films entire budget). Among  the 50s science fiction and horror films shot at Bronson Canyon are:  Attack of the Crab Monsters, Invasion of the Body Snatchers, Earth  vs. The Spider, It Conquered the World, The Brain from Planet Arous,  King Dinosaur, Invisible Invaders, Night of the Blood Beast, The  Return of Dracula, Robot Monster, Teenage Caveman, and Teenagers  from Outer Space. The canyon gained additional fame from the 1960s  Batman TV series for the exit of the Bat Cave (which was actually  used in filming Cadavra).
