Ben Wheatley’s Free Fire is as pointless an exercise in nihilistic violence as Seattle Screens have seen in some time. For some reason it’s set in the late 1970s, as a representative of the IRA played by Cillian Murphy (The Wind that Shakes the Barley) attempts to buy machine guys at an abandoned factory in Boston. The deal has been put together by Brie Larson (Room) and Armie Hammer (The Lone Ranger), the latter unrecognizable in turtleneck and beard. The dealer is South African actor Sharlto Copley (Chappie), leading a gang of ruffians, one of whom got in a fight with one of Murphy’s gang of ruffians the night before. When the two men recognize each other, they begin fighting, someone pulls a gun and soon the two sides are, as they say, freely firing at each other. Later some other people will show up and start shooting at everyone, but no one, apparently, knows why. One person will survive, of course, but it doesn’t matter who, or why, or for how long, though the final shot manages the unique feat of cribbing from both Reservoirs Dogs and The 400 Blows.
