"Game of Thrones" (HBO, March 31)
After cementing its standing as an audience and critical favorite in its first two seasons, HBO's "Game of Thrones" may be poised to take a next leap, if D.B. Weiss and David Benioff are able to hit a reasonable number of the targets from George R.R. Martin's third "Song of Ice and Fire" book, generally considered the best in the series. In addition to the vast returning cast, the third season will introduce new faces including Diana Rigg as The Queen of Thorns, Clive Russell as Brydon Tully, Mackenzie Cook as wildling Orell and Thomas Brodie-Sangster and Ellie Kendrick as Jojen and Meera Reed. There's so much awesomeness in "A Storm of Swords" that not only are the writers splitting it across two season, but this spring's episodes will be slightly longer-than-usual, almost the equivalent of a full bonus episode.
