10 More Disturbing Plot Twists In Non-Horror Movies

10. Snowpiercer - Gilliam Was In On It

Kicking off the list is this much-underrated plot twist from Bong Joon-ho's brilliant post-apocalyptic thriller Snowpiercer, which revolves around a train circling a frozen earth. With tragic inevitability, the train has become a segregated class society and those at the back of the train are living in squalor. Curtis (Chris Evans) leads an uprising against those in charge of the train. However, by the time he reaches the front, nearly all of his allies are gone, including his close friend and mentor, Gilliam (John Hurt). 

In the film's unforgettable final half-hour, Curtis finally meets the leader of the train, Wilford (Ed Harris), who reveals that Gilliam was actually allied with him. He and Gilliam conspired to incite a rebellion, and the purpose of this was actually to reduce the population of the train's tail-end to manageable levels. All along, Curtis was never really a revolutionary, he was just a plaything of those who ruled over him, and this twist was a clever way to hammer home just how corrupt and evil the Snowpiercer's society really was. 

Also, what a horrendous betrayal this was. Compared to this, Lando Calrissian stabbing Han Solo in the back looks like nothing.
