There just might be a lot more dragons and swords in HBO's future.
George R.R. Martin, whose "A Song of Ice and Fire" fantasy novel series served as the basis for HBO's hit drama "Game of Thrones," has entered an overall deal with the network.
The two-year agreement will retain Martin as a co-executive producer of the series, which begins its third season March 31, but will also have him developing and producing series for the network.
In addition to "Game of Thrones" -- which he's written a few episodes for -- Martin served as a producer and writer on the 1980s series "Beauty and the Beast," and penned a handful of episodes for the 1980s revival of "The Twilight Zone."
