Trivia

Warren said in a 1988 interview (about adding extra footage on foreign movies) with Tom Weaver, "I'd shoot one day on this stuff and throw it together...I was in the business to make money. I never, ever tried in any way to compete, or to make something worthwhile. I only did enough to get by, so they would buy it, so it would play, and so I'd get a few dollars. It's not very fair to the public, I guess, but that was my attitude...You didn't have to go all out and make a really good picture.".

He initially created his own films, although relying heavily on stock footage. Later, he would just buy foreign films that already existed and re-edit them, dubbing some scenes in English and inserting new footage which he shot with American actors such as John Carradine and Katherine Victor.

Warren produced an all-original film called "The Wild World of Batwoman" in 1966 which stars Katherine Victor and Bruno Ve Sota. He did not produce another film after that until he released his final motion picture, "Frankenstein Island" in 1981, starring his biggest name cast of Katherine Victor, John Carradine, Cameron Mitchell, Steve Brodie and Robert Clarke.

After creating and distributing the first four of his own films ( Teenage Zombies, The Incredible Petrified World, Terror of the Bloodhunters, and Man Beast) Warren decided that producing original features from scratch required entirely too much money and effort, so he began buying and distributing foreign-made films through his own distribution company, Associated Distributors Pictures Inc., or ADP. His first such involved purchasing the Swedish science fiction film Space Invasion of Lapland, and editing it into his own version re-titled "Invasion of the Animal People".

Jerry Warren was an American film director, producer, editor, screenwriter, cinematographer, and actor.

Warren was married to cinematographer Brianne Murphy. Warren and Murphy met in 1956 while Warren was preparing to film "Man Beast" and they married in Las Vegas, Nevada, after he finished the film. During the honeymoon, Warren wrote the script for "Teenage Zombies" in less than a week.

After meeting with producers, Warren took on his first film as a director and producer with Man Beast in 1956.

Warren often cut out all of a foreign film's dialogue and would shoot new scenes in which the American actors would try to explain the plot, sometimes using extensive voice-over narration, or adding scenes in which his actors would simply sit in front of the camera and just talk to each other.

Warren wrote some screenplays for his films under the pen name "Jacques Lecoutier", which he sometimes misspelled in the credits.

Warren was hired to film some extra footage in 1965 to pad out the running time of another American producer's film titled Blood of the Man-Devil which starred Lon Chaney Jr. and John Carradine. The film was later released to television as House of the Black Death.
