Several people may have heard of the first Relentless film, which raked in nearly 7 million dollars in box office receipts in the late 80's. But did you know that not long after that first movie, they made two more of them? Actually, they made three more but we love you too much to subject you to that amount of Relentlessness.

RELENTLESS (1989, William Lustig)
