American film director since 1958, primarily in the low budget exploitation field such as Angel’s Brigade," 1979 and "Mad Dog Coll," 1993. He directed several Al Fast productions, "Black Shampoo," "Satan’s Cheerleaders," 1971 and "Death Trap," 1974. As an actor, he played small roles in biker flicks and horror cheapies such as "Dracula vs. Frankenstein," 1971. While his work is not likely to come up for consideration before the Oscar committee, Clark's films have almost invariably posted big box-office profits.
During the '70s he was living with a sweet-dispositioned lady, Jackie, born 6/22/1947, 5:50 AM EST, Johnsonburg, PA, who played one of the lead roles in "Cheerleaders."
