Animated 'Snowpiercer' Prequel Explains WTF is Happening

If you saw the bleak, train-centric trailer for Bong Jooh-ho's "Snowpiercer," chances are you might've been at least a little confused about what the what was going on in it. This animated short, which serves as pseudo-prequel to the sci-fi drama should help clear a few things up.

First of all, let's break down the plot: In a nutshell, the film is set in the future, following a time when humans have failed in an experiment to stop global warming, instead inviting an Ice Age that destroys all life on Earth save for one train-full of people. This particular train is special, mind you, because it's got a perpetual-motion engine ... and that engine produces all the heat, so the front of the train is the place to be. Except, there's a stratus to this thing, and at the tippy-top of the heater hierarchy is Mason (Tilda Swinton), the frigid — pardon the pun — H.B.I.C. on this locomotive.

Naturally, revolution ensues, led up by Curtis (Chris Evans) and his freezing friends.

Adding to that info, this animated prequel helps to sheds some light on that "failed experiment" that covered the world in ice like this. Evidently, things were not so different than they are in real-life present day — iPads and 7up were apparently still in — except that to solve the issue of global warming, people weren't so much going for hybrid vehicles and rechargeable batteries as they were counting on a rocket called the CW-7 to launch away all their problems. It did not end well. Sort of a reverse Pompeii situation, from the looks of this thing.

The real drama and violence, though, followed with the selection of which people get onto the dang train before it was too late. The humanity!

Interestingly enough, the prequel is told from the perspective of a 17-year-old named Yona (Ah-sung Ko in the film), recalling the adventures of her father, who is presumably Kang-ho Song's Namgoong Minsu, the "security specialist" employed by Pine's Curtis to overthrow the wench up front.

What a ride.

"Snowpiercer" also stars Jamie Bell, Alison Pill, John Hurt, Octavia Spencer, Ed Harris and Luke Pasqualino and hits S. Korean theaters on Aug. 1. The film's domestic release date has not yet been set by its distributor, The Weinstein Company.
