We’ve come to expect the unexpected from the eclectic films of indie filmmaker Ben Wheatley, as his rule-defying style can twist and mould genre conventions to fit his dark directorial visions. His latest project, which he co-wrote with his wife Amy Jump, is 70s crime caper Free Fire. The action unfolds over just one night in a derelict umbrella warehouse in Boston, Massachusetts. When business associates Chris (Cillian Murphy) and Frank (Michael Smiley) team up with facilitator Justine (Brie Larson) for a dodgy deal with Vernon (Sharlto Copley), Ord (Armie Hammer) and their squad of gun-runners, the tension is palpable. Not even so-called allies fully trust one another, let alone enemies so when an argument breaks out, a brutal shoot-out ensues.
