This is a great thread! I'm a bit late to the party so my suggestions may not be Iron Monkey quality.
I didn't see Tony Jaa's "The Protector" of Ong Bak fame. I liked it better even.

There is an old artsy sudo martial artts movie The Bride with White hair.
http://www.amazon.com/The-Bride-White-Hair-Brigitte/dp/630502054X?tag=duckduckgo-d-20 Its not strictly a martial arts film so if you are looking for Iron Monkey or Tai Chi master/Twin Warriors, try something else.
Jet Li the Swordsman 2 is one I watched. I lost it in a move and remember being quite upset about it. Its been 12 years so I can't remember how it stacks up against other moves.
https://en.wikipedia.org/wiki/Swordsman_II Jet Li has one called "My father is a hero" thats worth a watch.
http://www.amazon.com/My-Father-Hero-Li/dp/6305131422?tag=duckduckgo-d-20 Jet Li "Once upon a time in China" . The first I liked. The others were harder to get into. You have to like such things quite a bit to get through Once upon a time in China and America.

Donnie Yen and Michelle Yeoh are in "Wing Chun."

The movie is a bit whatever, but Jackie Chan has a great fight scene at the end of "Who am I?" There is also this fast little guy he fights in "Gorgeous." That scene is also worth watching even if you don't want to sit though the cheesy love story
Thats it for now.....for now.
Oh and I'm interested in Chocolate. Be curious to know if anyone has seen it.

There is a good chance people will not agree with me on this one but I always like "Drive."

Its probably the best English fighting movie I've seen. Don't take the story any more seriously than you would any Chinese movie and you should be fine.
I'm starting to hate this tread already. I've lost half of the movies on my list.
