The success of HBO's Game of Thrones has made George RR Martin arguably the most recognisable and in-demand fantasy writer in the world.
But while fans and TV producers wait for the 67-year-old to finish the next book (he has two left), perhaps they should look to his back catalogue for the next big-screen adaptation instead.
Dying of the Light (1977)
Martin's first full-length novel was nominated for both the Hugo Award for Best Novel in 1978 and the British Fantasy Award in 1979. The "space opera" is set in the far future on Worlorn, a dying rogue planet that is drifting away from its suns.
This sci-fi/fantasy novel was co-written with the novelist Lisa Tuttle. The inhabitants of the planet Windhaven are the descendants of human space voyagers who crash-landed there centuries earlier.
Fevre Dream (1982)
A vampire novel set on the Mississippi River in the 1850s. A struggling riverboat captain becomes the business partner of a mysterious aristocrat, who, it emerges, is on a quest to free his vampire brethren from their dependence on humans for nourishment.
The Armageddon Rag (1983)
A mystery-fantasy novel structured in the form of a murder mystery. The author described the book as "a total commercial disaster" that almost destroyed his career.
Hunter's Run (2007)
An expanded version of an earlier novella, Shadow Twin, Martin co-wrote this science fiction novel with Daniel Abraham and Gardner Dozois.
