The third season of the HBO fantasy drama will receive its UK premiere just one day after US transmission.
The transmission pattern follows last year's UK screening of season two, which also premiered new episodes the day after US airing.
The third Game of Thrones season - which star Kit Harrington (Jon Snow) has described as the most epic yet - will be comprised of ten "super-sized" extended episodes.
Rome's Ciarán Hinds, Torchwood actor Burn Gorman, Dame Diana Rigg, The Office star Mackenzie Crook and Waking the Dead's Tara Fitzgerald are among the stars to have joined the show for the new season.
