I am a Donnie Yen fan, even before the Ip Man movies on Netflix. Which, by the way, all 3 of his Ip Man movies are on Netflix, in Chinese with subs mostly. I actually started following him on the martial arts competition circuit. The dude is fully legit, mixed street fighter-esque with real-world fighting experience. Awesome to watch his bouts. Even as he is getting older I bet he would absolutely kill in MMA.
I haven't seen the Ip Man films, admittedly that's not really my genre (haven't seen Ong Bak neither), but I did enjoy Donnie in this one, he has kinda unique character.
