Snowpiercer is the best film you haven't heard of.

Set in the near future after the second ice age, the remnants of humanity have retreated onboard a giant train whose tracks circle the frozen Earth.

Life aboard the train is divided into clear classes, with hardship and poverty for the proletariats at the back and sweaty raves and sushi for the front. After 17 years under the thumb of the train's mysterious engineer Wilford, Curtis (played by Chris Evans) leads a group of insurgents towards the front in an attempt to restore the balance of power. Snowpiercer blends the bleakest dystopia with enough twisted wit and superbly shot action to make it as provocative as it is compelling.

Despite the massive grudge match that hampered its release - it was considered too long for American audiences - it's now being made into a TV show. Here's what we know: it will be set 10 years before the film, Boon Joon-Ho (the film's director) will produce it, and Josh Freidman will be the writer and showrunner.

I, for one, am pretty excited about this. Despite the disappointing ending, the film still managed to leave me wanting more.

More Tilda Swinton

Because TIlda Swinton should be in everything. Don't try to tell me I'm wrong.

More backstories

Ok, so I know that it's unlikely that the TV show will have Tilda. But I demand more of her character Mason, the toothy bureaucrat that perfectly blends Margaret Thatcher and Deirdre from Coronation Street.

Curtis provided an easy entry point into the Snowpiercer world, and it was his journey that carried us through the film. The film gave us some many great and messed up characters but any insights into them are only really offered up when they contribute to Curtis' development. As much as I would love to see more of Chris Evans on my TV screen, I would love even more to find out about everyone else and how they earned their place in Snowpiercer's horizontal hierarchy.

More social commentary

Snowpiercer is a sci-fi parable that presents us with a straightforward parallel with society. The film races through each carriage at such a pace that it doesn't really have time to explore any of these ideas or aspects of its society in any real depth. The episodic nature of TV show would lend itself to exploring the microcosm of each carriage's social class.

The characters of Wilford, Mason and Gilliam (Curtis' mentor and Wilford's conspirator) offer a glimpse into the subtleties of power. Wilford is the benevolent dictator, kindly allowing people continue living while using Mason as the rod and Gilliam as the manipulator to maintain balance.

More big ideas

Rather than making any political commentary, Snowpiercer instead chose to instead ask bigger, more philosophical questions about the nature of society. I'm still not 100% sure this was a good thing, the nature of the medium plus the sci-fi action genre makes it difficult to explore this with any subtlety. Like woah, the cogs of capitalism are literally oiled by the blood of the working classes.

The show will allow Friedman to make a more measured argument for this - he can really drill down into the nuances of power. What makes people devoutly follow their leader? And just how much are people willing to deprive others of in order to maintain their own lifestyle?

But the show doesn't just present the opportunity to open up the idea of power and oppression. The film also touched on the problem of overpopulation (Wilford and Gilliam's plan for revolution was to cull the growing number of passengers), while the original comic book was also concerned with environmentalism and climate change.

More over the top silliness

Three big themes could quite easily leave the series feeling bloated and self important, so finally the series needs to keep the things that stopped the film from buckling under its own weight. Snowpiercer needs to keep the keep the bloody brawls, ridiculous yet straight-faced monologues about eating babies, and the twisted and inventive punishments for civil disobedience. Above all, it just needs to go nuts.
