With "Game of Thrones" ending its run on HBO next year, everyone's trying to keep George R.R. Martin's work on television.

This time, it's Hulu, which is developing multiple series based on "Wild Cards," a sci-fi shared universe edited by George R. R. Martin and co-edited by Melinda M. Snodgrass and consisting of anthologies and solo novels by more than 40 authors.

In this shared universe, an alien virus released in 1947 has rewritten the DNA of some of its victims, turning them into mutants with either super powers (called Aces) or crippling physical defects (called Jokers). The two most recent additions to the universe, "Texas Hold ‘Em" and "Low Chicago," were released earlier in 2018.

"Wild Cards" initially originated from a long-running campaign in the "Superworld" role-playing game, gamemastered by Martin and involving many of the original authors.

Martin and Snodgrass will executive produce the shows developed by Hulu, which has opened a writers room for the project.

Martin will say farewell to the hit HBO adaptation of his most famous work, "Game of Thrones," when the final season premieres in April 2019. He also serves as an executive producer of the Syfy adaptation of his novella "Nightflyers."
