Chuck Norris stars as the only martial artist alive who can take down a ninja clan, (led by his adopted brother) in this very dull ninja movie which earns a couple points for the inspired performance of Lee Van Cleef. Chuck Norris made only one ninja movie in his career (I think because I don't remember any others) but somehow The Octagon is a surprisingly plot driven ninja movie which isn't a very good thing since well ninja movies need to be swift. When it comes to ninja movies, it remains vastly inferior to American Ninja (And it's first sequel) and Revenge Of The Ninja which could quite possibly be the birth of the genre. The Octagon has a few moments but generally Norris' voice-overs and complete lack of action make this for Norris enthusiasts only.
