Video: HBO teases A Game of Thrones

The first teaser for the upcoming Game of Thrones aired tonight, targeting the True Blood faithful. The video is very blink-and-you’ll-miss-it, but you can head over to the official page (or the fanblog Winter is Coming) for a good look at Sean Bean in costume.

Since we last checked in, a few roles have been recast: Michelle Fairley has stepped in as Catelyn, and Emilia Clarke as Daenerys. Filming is due to start in July.
