He was great in JCVD (2008), but most of his other movies weren't that good in terms of acting with a few exceptions.
It was always all about his fighting scenes which were actually really amazing. I did like his older movies though (1988~1999 era)
Bloodsport, Kickboxer 1, Universal Soldier 1, Lionheart, and stuff, were awesome.
Also, here's one of my fav. scenes of Jackie Chan in the movie "Who Am I". The fight on the rooftop.
1. Bruce Lee
2. Jeff Speakman
3. Tony Jaa
4. Michael Jai White
5. Bolo Yeung









Tony Jaa is on the road to self destruction. I've lost faith in him completely.
Personally I like Ray Park. He must be the most underrated martial artist ever.
