George R.R. Martin Is Working On Another TV Show With HBO

Acclaimed author George R.R. Martin is keeping very busy. In addition to finishing the seventh A Song of Ice and Fire book, he's consulting on the Game of Thrones TV spinoffs and contributing to the video game Elden Ring. Now he's involved in another project.

Deadline is reporting that Martin will be an executive producer on the new HBO adaptation of the sci-fi story Roadmarks from writer Roger Zelazny. Star Trek: Discovery's Kalinda Vazquez is adapting the book for HBO, and she is is the writer, executive producer, and showrunner.

At the center of the Roadmarks novel is a highway that doubles as a time machine. Those who can find this highway can use it to reach different timelines of history to discover the mysteries of the world and change the past to alter the future. Naturally, things go sideways.

Martin is no stranger to Roadmarks, as he met Zelany in the '70s and they became friends before they both moved to the Santa Fe, New Mexico area. Zelazny died in 1995.

In addition to Martin, Game of Thrones producer Vince Gerardis is producing the Roadmarks adaptation at HBO.

Martin also previously adapted Zelazny's Last Defender of Camelot for a 1986 episode of The Twilight Zone. In a statement, Martin said he's looking forward to working on Roadworks and getting a chance to extend Zelazny's legacy.

"Roger was a friend, a mentor, and one of the greatest science fiction writers who ever lived," Martin said in a statement. "It was an honor to be able to bring his work to television. That is why I am so thrilled to be a part of adapting Roger’s novel Roadmarks for HBO. We have a great book, a great screenwriter in Kalinda Vasquez, and the makings of a wonderful, original show. I look forward to a long and thrilling journey.”
