Update: HBO has officially released the trailer for Season 5. You can watch it here.
Viewers who attended HBO's IMAX screenings of Game of Thrones' Season 4 finale last night got a big bonus when it was all over: a first look at the trailer for Season 5. HBO hasn't put the trailer online yet, but it looks like one theatergoer took the opportunity to record the trailer at their screening and publish it on YouTube. The recording quality is actually a lot better than what you'd expect for something like this, so this "leak" may be enough to hold you over until the real thing comes out — whenever that happens. The new season starts on April 12th.
