7. Enter the Ninja (1981)

Have to have at least one film that features Sho Kasugi, the lord of all Ninja actors. He starred in Ninja III: Domination, Pray for Death, Revenge of the Ninja and Rage of Honour. He was also in Blind Fury. He'll be in the new Ninja Assassin as Lord Oznu, which is pretty much like getting Charlton Heston in the Planet of the Apes Remake (although hopefully the movie will be better - certainly will have more Ninjas). Enter the Ninja is of course a play on Enter the Dragon, but bears little resemblance in plot or production value. It starred hairy Italian actor Franco Nero (yup!) in the title role.

6. The Super Ninja (1982)

When it comes to the 'so bad it's good' category, The Super Ninja comes close to providing you with everything you've ever wanted in terribleness. Also known as Five Elements Ninja, it's directed by Kuo-Ren Wu and stars Alexander Lou. Combining elements from bad porn, bad gangster movies, and of course, bad ninja movies, the plot beggars belief in both continuity and logic as five evil ninjas and a host of bad guys ranging from corrupt cops to er... ninjas must eventually bow down before the superior Ninja skills of The Super Ninja."

5. American Ninja (0%)

Produced by the Cannon Group, who seemed to provide almost every single B-grade action movie for the 80's (including a few A-Grade ones), American Ninja stars another variant of the Ninja format - the 'white' Ninja. Starring the rather impressively named Michael Dudikoff this translation of the Eric Van Lustbader novel (the names just get better and better) it shows that a 'foreign devil' can train well enough to defeat the ordinary Ninja - in this case, Joe Armstrong (name, again!) has to rescue his girlfriend from an evil overlord and his private Ninja army. It spawned four sequels!
