Game of ThronesWesteros is going big - very big.

"Game of Thrones" is heading to IMAX for one week, starting January 23, where fans can watch two digitally-remastered season 4 episodes, "The Watchers on the Wall" and "The Children." As a bonus treat, an exclusive season 5 trailer will screen with them.

"The cinematic brilliance and grand scope of the series is perfect for the IMAX format," said HBO chief marketing exec Pamela Levine. "We are always looking to provide fans with new and exciting ways to experience the show and viewing two key episodes, along with the new trailer, on such an impressive platform makes for a great event."

The sweeping, epic drama is a good choice to be the first television show to screen on IMAX. Tickets will go on sale soon.

"Game of Thrones" season 5 returns this spring, likely in March or April. HBO has been teasing fans with brief glimpses, but so far, all we know is that Bran Stark won't be featured this season and there will be a flashback involving a dead character.
