Winter is coming — to the big screen. HBO and IMAX have partnered to bring several episodes of Game of Thrones to theaters, along with a new trailer for the upcoming fifth season. The final two episodes of season four have been remastered for the format — making them the first TV episodes showcased in IMAX — and they'll be airing with the new trailer in 150 different IMAX theaters throughout the US starting on January 23rd through to the 29th. (Tickets are expected to go on sale at imax.com soon.) HBO has been slowly teasing season five of the show since late last year, with the first episode set to debut in April.
