The daily grind of office work can often seem like a fluorescent hell. Trust Greg McLean, Australia’s pre-eminent horror auteur, to take that to its literal conclusion ... with a little help from Guardians of the Galaxy director James Gunn!

Way outside Bogota's city limits, a mysterious company known only as Belko Corp announces to its staff that today's work day is going to be a little different. Today they'll be playing a game wherein most of them will die. If they want to survive, all they have to do is follow the instructions. The first instruction: pick and kill two of their own.

So begins horror maestro Greg McLean's fiendishly inventive and swaggeringly gruesome The Belko Experiment. Created together with in-demand Hollywood screenwriter James Gunn (Guardians of the Galaxy Vol. 1 & 2) – consider this the passion project – The Belko Experiment plays out as a Battle Royale for the office block set, a work of relentless set pieces, pitch-black humour and richly imagined violence that firmly establishes McLean (who also directed the MIFF 2017 Opening Night film, Jungle) as Australia's modern master of take-no-prisoner thrills.
