Game of Thrones creator George R.R. Martin is developing a new TV series for HBO entitled Captain Cosmos. The author has an overall development deal with the network, but, for those fans worried that this will take time away from his sixth Game of Thrones book, the series isn't expected to be a big time commitment for the writer, according to The Hollywood Reporter. We reported last month that the author is skipping a number of conventions this year, including Comic-Con, to focus on his long-awaited Game of Thrones book entitled The Winds of Winter.

Michael Cassutt, a writer and executive producer on Syfy's Z Nation, is writing the pilot script. The story centers on a young sci-fi writer in 1949, in the dawn of the TV age, who spends his time creating stories that no one else would dare to tell. No further details were given regarding the plot at this time.

Before writing his Game of Thrones novels, George R.R. Martin previously wrote for the 1980s TV shows The Twilight Zone and Beauty and the Beast. George R.R. Martin has also written one episode for each of Game of Thrones' first four seasons, but he is taking this year off, to focus on The Winds of Winter.
