Round 1: Match 9
Hai vs. Ricky
Movie: Riki-Oh

While the head crushing may be the most iconic image from the movie, this is the fight everybody remembers. Ricky tying his tendon back together with his teeth, Hai choking Ricky with his own guts, it's all so bloody and violent and over the top. Hell, they're fighting beneath a crucified guy. One of the better kung fu movies in its over-the-top-ness
VS
The Saints vs. Il Duce
Movie: The Boondock Saints

The only real gunfight in the movie. The rest are just massacres. Yes, it uses some of the same clichés the brothers themselves mock earlier in the movie, yes, Dafoe's prancing about and firing the gun in the air is silly if you really think about it, but who cares? The first time you see Il Duce with his gun vest and the cigar and sun glasses, it's way awesome.
