In an online documentary for this movie, Michael Dudikoff recalled that when it came time for him and Steve James to jump off the large boulder at the end of the beach fight scene, James quickly whispered to Dudikoff that he didn't know how to swim. Dudikoff then told him that that was a serious problem and shouted out to the crew to halt filming. They then brought on James' stunt double to do the jump, but he also admitted that he didn't know how to swim, either. James then did the jump himself with Dudikoff promising that when they both hit the water he would grab James and pull him up to the surface.
Although the original film was one of Cannon's few hits, the company greatly slashed the budget for this sequel when it hit financial trouble.
Prior to the film's release in 1987, several cuts had to be made in order to receive its "R" rating due to excessive close-ups in various fight scenes.
The only time any of the ninjas wear the crest logo of The Lion is inside and around The Lion's compound.
The last movie Michael Dudikoff made with Menahem Golan and Yoram Globus, but not the last one he made with Cannon. That was Chain of Command (1994).
