"one of the best characters I ever played. I played him kind of insane and what was wonderful was the one of my reviews compared me to Stanley Holloway in one of his Shakespearean gravedigger roles." AIP's special effects artist Paul Blaisdell was drafted to play the corpse in the coffin in the graveyard scene, which he said was a lot of fun. His eyes however were supposed to remain open and staring throughout the scene, and he said it was difficult because little particles of the coffin lid kept falling into them like dust. Shooting Filming started 26 July 1956. The movie was filmed in a converted supermarket, and was completed in only ten days, according to Griffith, costing $70,000.

The bats that the imp and witch continually change into were left over from another Corman movie, It Conquered the World. Griffith says the film was "a fun picture to shoot...

Welles recalls "we almost died of asphixiation from all the creosote fog that was created in" the supermarket. Devon said "They had a bee-smoker to create the dreadful-smelling fog." Some exteriors were shot at a place called The Witch House in Beverly Hills. The movie was the first of several Devon made with Corman.

Anything that cost a penny over his minuscule budget turned him into a monster... He was Just screaming his head off. Everybody was telling him that it could be rectified, and I said [calmly], "Roger, it’s all right, don’t worry about it. We’ll get somebody to write it out on a card or something and I’ll read it."
