Ready for the best trailer you'll see today - if not this year? Discover Iron Sky: your new favourite movie about Nazis from space.

A Finnish science-fiction comedy film, it's utterly preposterous romp through space, time and history itself, chock full of cardboard cut-out German villians who decide to destroy the world from their base on the dark side of the moon.

The plot - for what it's worth - sees a Sarah Palin lookalike battling against said moon Nazis as they launch their space Zeppelins at humanity's favourite planet. Excited? You should be.

But if you're looking for star power, it doesn't really have any. And if you're looking for a plot that makes any sort of sense, it doesn't have that either. What it does have, however, is a moon base in the shape of a Swastika, massive spaceships and some of the most joyfully hammy acting ever.

So without any further ado, here's the trailer for Iron Sky - and if you're looking for the date to write down in your diary, it's out in the UK on 20 April.
