... and you've seen the complete works of the guys who made big names in Hollywood? If Jackie Chan and Jet Li are old hat for you, and you've seen Crouching Tiger, Hidden Dragon more times than you can count, you might want to take a look at the library catalogue! True story. You could start with searching a few other big names: Chow Yun-Fat, perhaps.
But sometimes the simple solution will turn up some great stuff. In this case, searching under "kung fu" and narrowing down your list from there to adult DVDs turns up a whole bunch of goodies. Who knew, right? About 2/3 of them are in chinese, but if you just want the action and don't care about understanding the dialogue, this is what you want, right here.
You can dig a little deeper by searching for subsets of kung fu. Shaolin? Turns up a nice little list, including some of the same titles as above, and some new ones, nearly all in chinese, again, and some of it nicely obscure for those connaisseurs among you - and also, of course, the more Hollywood Shaolin Soccer.
Happy hunting - and to help spread the love for good action flicks, share your favourites in comments for someone who may have missed out on them!
