We learned earlier this summer that Showtime is developing a small screen adaptation of the Halo video game franchise, ordering a season of 10 episodes back in June. The project is said to be Showtime’s “most ambitious series ever,” promised to “enthrall fans while also drawing the uninitiated into a world of complex characters that populate this unique universe.”

Speaking with IGN this week, Showtime president of programming Gary Levine just teased some more details about the upcoming series.

“It is a new story but we are being incredibly respectful of the canon and working with the Microsoft 343 people to be sure we don’t violate any of that,” Nevins told the site.

“It is a very different genre, it’s futuristic, space-based science-fiction, it’s not fantasy,” he continued. “It took us a long time to get the script but we felt like we had something that was really interesting and felt like it belonged on Showtime in terms of its character depth, and it’s gonna be a big show.”

The series is expected to arrive sometime in 2020.

Kyle Killen (Awake) will be serving as executive producer, writer and showrunner, while Rupert Wyatt (Rise of the Planet of the Apes) will direct multiple episodes and also executive produce. The show will be produced by Showtime in association with Microsoft/343 Industries, along with Steven Spielberg’s Amblin Television, with production starting in early 2019.
