This could mean they will end up developing a superhero anthology based on Wild Cards, or a Thrones prequel derived from his Tales of Dunk and Egg.
Or we could be seeing his space trader Haviland Tuf make his way to the small screen.
Tuf Voyaging is a so-called "fix up novel," a longer work patchworked from pre-existing shorter pieces. It tells stories of interplanetary travel on board "the ark," a terraforming warship.
The book has been recently reissued, prompting to Martin to write about it on his blog. As well as promising fans that he'd like to write more Tuf tales at some point, he also addresses the possibility of it becoming a TV show:
It has also been suggested that I make TUF into a TV series. Hey, love to. But it's not up to me. I need to find a studio and network willing to back a new space show to the tune of many millions of dollars, and that's not easy. I have pitched Tuf before, and hope to pitch him again, Real Soon Now, but honestly, he's a tough sell. Television likes its starship captains sexy, like Kirk and Captain Tightpants and Rocky Jones. Tuf is a towering, hairless, fat, pompouse fellow who talks like Alfred Hitchcock and loves pussycats. Not an easy part to cast either… but hey, every time I see Conleth Hill playing Varys [in Game of Thrones], I go "Hmmmmmmmm."
"Real Soon Now, " he says. That would be with HBO, I'd imagine – or otherwise, I don't know what the point of their deal would be.
Well, consider this the first show of support for the idea. I'd certainly watch a good, well-made Tuf Voyaging TV series, and Conleth Hill doesn't seem like bad casting at all.
HBO really shouldn't be worried about their lead character looking so "un-TV," but if they do get tied-up over this, surely they could just "make up for it" with a pin-up ready supporting cast.
