While most of the actors were experienced, some even having lots of credits on stage and film, they had to work hard to give an honest B movie performance.
Most of the props were purchased on eBay. Others were inexpensive props made of household items like toilet paper tubes, candle holders and caulk guns. A number of props were obtained by looking around the cabin in which part of the film was shot, including the mashed potatoes the cast are seen eating.
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 film's entire budget). Among the 50s science fiction and horror films shot at Bronson Canyon are: Attack of the Crab Monsters (1957) , Invasion of the Body Snatchers (1956), The Spider (1958), It Conquered the World (1956), The Brain from Planet Arous (1957), King Dinosaur (1955), Invisible Invaders (1959), Night of the Blood Beast (1958), The Return of Dracula (1958), Robot Monster (1953), Teenage Cave Man (1958), and Teenagers from Outer Space (1959). The canyon gained additional fame from Batman (1966) for the 'exit' of the Bat Cave (which was actually used in filming 'Cadavra').
To mimic the classic B&W look, they filmed in color using a miniDV camera and stripped the color in postproduction.
