Winter is coming on March 31st and sure tis bringing a whole lotta Game of Thrones themed chaos with it. Guess it's time for Tyrion Lannister and the gang to get back to business.

A new teaser trailer for Season 3 of HBO's hit series dropped this morning fearturing all of the show's main characters like Tyrion (Peter Dinklage), Daenerys (Emilia Clarke), Jon Snow (Kit Harington) and Robb Stark (Richard Madden). We spied our own Jack Gleeson in there too - he's just TOO good at being evil.

It's a rather dark little 40-second teaser that hints that there's trouble ahead in this extra special third season. There will be lengthier episodes on offer as the gang tear through the first half of George R.R. Martin's 'A Storm of Swords'.

Martin recently signed a deal with HBO to stay on for two more years, but we can't help but wonder if he's going to run out of books before the show ends?

Game of Thrones returns to Sky Atlantic on April 1st 2013.
