I'd recommend Once Upon a Time in China I, II, and III
Or, better yet, watch all three of them, marathon style (i did that with some friends a few weekends ago.
We watched them on my projector, so the electron beams didn't burn my eyes out, but I didn't crawl out of bed until late afternoon the next day.
Good movies! Jet Li kicks some major tail. They rock even more if you are learning mandarin (and so are the friends you watch it with), because mandarin is one of the audio tracks. So you get foreign languaged, lip-synched (it was originally filmed in Cantonese), kung-fu action. What more do you want?
