When Shapiro Entertainment Corporation picked up the movie for its release, the distributor ordered director Don Bendell to shoot and insert a new opening to make the film more action-packed and to give it more character development. The new opening consisted of Thumper and Bob Chaney's character engaging in a no-holds-barred fight with a street gang. Another sequence occurs at the same time when a group of playground kids battle a seemingly normal guy creeping around, disguised as a ninja. The ninja later shows up after the fight and Chaney offers to let him join his karate school, to Thumper's dismay.
