What's the best tae kwon do you've seen in a movie?

"Best of the Best" comes to mind of course, especially the phenomenal Philip Rhee and Simon Rhee (unrelated?)

But the really kickbutt guys are in Hong Kong cinema, specifically Koreans Casanova Wong and especially Huang Jang Lee. I also think of the Taiwanese master-disciple guys in Tan Tao Liang and his disciple John Liu (Liu looks exactly like an unrelated aunt of mine).

The white guy fighting Jackie Chan at the end of "Who Am I" was also really terrific. Killer moves!
