Cheh Chang's Shaolin Cycle (Heroes Two, Men From the Monastery, Five Shaolin Masters) but set before all of them, Death Chamber is a pretty good movie.
of course, Cheh is far more interested in telling a story than in any strict continuity between these four movies (and there are some others about the same people as well). some of the actors reprise their roles from the other movies, though Sheng Fu can't play two roles at once, as talented as he was.
there is plenty of training sequences and then the final battle is quite good.
it sure takes a lot to get into Shaolin, that's for sure!
