Tigershark (1989) - Human Cockfighting Scene 

American Ninja 2's Mike Stone starred in Tigershark, an obscure shot-in-the-Philippines DTV actioner about a martial arts instructor out to rescue his girlfriend from a jungle warlord. Can't say the film is really worth seeking out, but it does boast this unique take on the typical martial arts battle typically seen in these films that really does feel like human cockfighting with humans in place of roosters.
