'Game of Thrones': Finally, a full-fledged preview of HBO's new series

sean-bean-game-of-thrones.jpgHBO had been pretty stingy with sneak peeks of its new series "Game of Thrones" -- but that ended on Sunday.

Prior to the season finale of "Boardwalk Empire" Sunday night (Dec. 5), HBO aired a 10-minute making-of/preview special for "Game of Thrones." It was the usual mix of teaser footage, behind-the-scenes info and talking heads with the cast and crew -- but it was also the first extended look fans have gotten at the show.

The video -- which features interview segments with author George R.R. Martin, whose novels form the basis of the series, as well as creators David Benioff and D.B. Weiss -- is at the end of the post. But we also wanted to share a few new photos HBO has posted of the cast. Up above is Sean Bean ("The Lord of the Rings") as Eddard "Ned" Stark, and below is Lena Headey ("Terminator: The Sarah Connor Chronicles") Cersei Lannister:
