Bullet in the Head (1990) - John Woo 

What a remarkably brilliant over the top follow up to The Killer. John Woo reportedly wanted to make this A Better Tomorrow III, but Tsui Hark took the franchise from him, but that probably works best for this film. A trio of friends are forced to leave Hong Kong and decide to make a quick buck exploiting the situation in Vietnam. What follows is almost a Hong Kong interpretation of Treasure of the Sierra Madre, at least that's what I gathered. The film is epic in scope spanning two countries, several years, and an awful lot of explosions. It's a credit to Woo how he can take us from light hearted friendly mischief to tragedy by film's end. Certainly enough to encourage me to dig deeper into genre film making. I also ran out of Brazilian films.
