Few game franchises have stood the test of time as “Halo” has over the years. Now the story of the militant Spartans and the deadly alien threats that they battle will be told through a new series on Showtime. According to the network’s announcement, Showtime has ordered 10-episodes of a live-action, scripted drama, which is currently being called “Halo” but that is a working title. The series will be based on the best-selling Xbox franchise, with Kyle Killen (Awake) serving as executive producer, writer and showrunner.

Also working on the series is Rupert Wyatt (Rise of the Planet of the Apes) and Showtime has confirmed that he will direct multiple episodes and also executive produce the hour-long series. Produced by Showtime in association with Microsoft/343 Industries, along with Steven Spielberg’s Amblin Television, HALO will begin production in early 2019. The announcement was made by David Nevins, President and CEO, Showtime Networks Inc.

Halo is one of the best-selling video game franchises of all time, having sold more than 77 million copies worldwide and grossing more than $5B in sales. In its adaptation, the series will take place in the universe that first came to be in 2001, dramatizing an epic 26th-century conflict between humanity and an alien threat known as the Covenant. HALO will weave deeply drawn personal stories with action, adventure and a richly imagined vision of the future.

“HALO is our most ambitious series ever, and we expect audiences who have been anticipating it for years to be thoroughly rewarded,” said Nevins. “In the history of television, there simply has never been enough great science fiction. Kyle Killen’s scripts are thrilling, expansive and provocative, Rupert Wyatt is a wonderful, world-building director, and their vision of HALO will enthrall fans of the game while also drawing the uninitiated into a world of complex characters that populate this unique universe.”

In addition to Awake, Killen created and served as showrunner of the TV series Lone Star and Mind Games, and also wrote the feature film The Beaver (directed by Jodie Foster). In addition to Rise of the Planet of the Apes, Wyatt’s film and television credits include the upcoming sci-fi feature Captive State, as well as The Exorcist, The Gambler, Turn: Washington Spies and his debut feature film The Escapist, which was nominated for a British Independent Film Award.

HALO will be executive produced by Killen, Wyatt and Scott Pennington, along with Justin Falvey and Darryl Frank for Amblin Television. The series will be distributed globally by CBS Studios International.
