Along with writing the insanely popular A Song of Ice and Fire series, George R.R. Martin is also spent the last few decades overseeing a series of anthology books known as the Wild Cards series. There are currently twenty-two of these books out, with a twenty-third well on the way.
Martin contributes to the series, but a bunch of other writers do as well. The series’ world is one in which an alien virus hits the Earth in 1946, killing 90% of the population. Remaining humans become either deformed or basically meta humans. The premise sort of offers genre writers an open season to just go crazy.
And now it looks like they're developing the property into a television show, or shows. According to Martin’s Liveournal page, so coming from the man himself, Universal Cable Productions has purchased the rights to adapt the series, hopefully in multiple interlocking shows, which sounds pretty cool and ambitious. Martin cannot be directly involved because he is exclusive to HBO, but his “right-hand man” on the series, Melinda M. Snodgrass, will be an executive producer.
As long as everyone knows this probably won’t be much like Game of Thrones, there is a lot of potential for great superhero television here. It’s a world where pretty much can happen, and I’m willing to be that pretty much everything will. Hopefully this develops quickly.
