Winter is comingâ¦this spring. Anticipation for the third season of HBOâs wildly popular fantasy series Game of Thrones began just seconds after season two came to an end, and now the network has announced the season three premiere date with a crafty teaser poster. We know that the upcoming 10-episode season will cover roughly the first half of George R.R. Martinâs third book in the âSong of Ice and Fireâ series, A Storm of Swords, and Irish actor Ciarán Hinds (Tinker Tailor Soldier Spy) portrays the highly anticipated Mance Rayder (aka âThe King Beyond the Wallâ). Iâm plenty thrilled to delve back into the Game of Thrones world, so March 31st canât get here soon enough.Hit the jump to check out the teaser poster, and click here, here, and here to peruse our previous set photos from season three, and click here to watch Steve's recent interview with Jon Snow himself, Kit Harington.Via the showâs Facebook page.  Click to enlarge.
