Ben Wheatley may not be the most easily digestible director making a name for himself today, but as the man behind movies as varied as Kill List, Sightseers, A Field in England and High Rise, I'd find it hard to argue that he isn't one of the most interesting. His films are never short of originality, often bursting onto the scene less like a breath of fresh air and more like a hurricane of different, and Free Fire offers no exception - set almost entirely within the confines of an abandoned warehouse, we follow two groups of colourful, vibrant characters as they engage in an absurd shootout that, barring a short set-up, lasts for the films entire running time.
That set up sees a group of IRA members travelling to Boston in the 1970s to buy a bunch of assault rifles from South African arms dealer Verne, but the details of why this deal is happening are nothing more than set dressing for a film that really only exists to ask and answer the question of "can a single gunfight in one location really be turned into a feature length film?". In that respect, it could be argued that Free Fire is more interesting as an experiment in storytelling than it is as an actual movie - but that doesn't mean that it's ever less than a very entertaining film too.
