The Belko Experiment

In this cinematic anti-masterpiece, a corporate headquarters goes on lockdown, and it turns out all the employees have remotely-triggered explosives implanted in their heads, when a voice comes over the loudspeaker and gives them challenges that require them to kill each other or be killed themselves, apparently because, movie. An exceptionally violent, bloody, pointless movie, just violence as entertainment, but, for one of those, actually kind of good cheezy fun. John C. McGinley plays a slightly different character than he usually does, which is fun.
