You know nothing, Jon Snow (about IMAX releases, probably)YouTube

​​ Today is a big day for teasers: "The Walking Dead" just released a teaser for the second part of their season, and not to be outdone, HBO released a trailer for the "Game of Thrones" IMAX extravaganza that includes, at the very end, a teeny tiny bit of footage of the new season. So, if you were particularly worried about the one specific character on the show, you can see what's going on with him! Or you can stick it out another couple of weeks for when the full trailer actually hits the web.
