What's this film all about? It just doesn't make sense! It's like two separate films merged into one! Well funny you should say that...
Godfrey Ho was notorious for creating "new" movies by splicing together footage from obscure Asian martial arts films with new footage including Western actors, often those films are awful and completely incoherent but Ninja Terminator somehow works.
What makes it magic no doubt is the 1980s cheese, including tiny robots sent to give warnings, a Garfield telephone and ninjas teleporting their way through a fight scene.
The "other" film stars Jaguar Wong and has some really tasty kung fu action, with amazing fight after amazing fight. Really this film is all about fighting, take the fighting out of this film and you'd have about 5 minutes of footage. The splicing has been very well done so at times you do feel the film was all made in one go.
The ninja part of the film, with Richard Harrison as the main "ninja", leads up to an excellent conclusion. I have to say this is in my top 10 movies and my favourite ninja movie. I'm sure we all have one?
