Fireball

Here's a Thai martial-arts thriller based around an (I assume) fictional sport that's not likely to get accepted for the Olympic Games any time soon. "Fireball", or "muay thai dunk" as the subtitle has it, is a sort of homemade kill-or-be-killed version of basketball: one basket wins, but players are allowed to maim or murder opponents at will. There's some hastily thrown together story about a recently released convict looking to avenge his twin brother who has been battered into a coma (Preeti Barameeanat plays both roles), but ­really this is all about glistening pretty boys laying into each other in increasingly elaborate ways. (There's an ­unmistakable homoerotic undertow to all the glowering forearm smashes, too, unless I'm imagining things.) ­BASEketball this isn't.
