Take a trip back to May '13 with me. Microsoft is introducing their latest XBox One gaming console, and smack dab in the middle of their already gigantic presentation, they drop a nuclear weapon on nerds everywhere: Steven Spielberg is developing a live-action Halo series.
This obviously wasn't the first time a film or series has been kicked around using the hugely popular first person shooter as the source. Peter Jackson was developing a feature for years (with Alex Garland and D.B. Weiss attached as writers), but it turned out to be way too expensive. Neill Blomkamp even made a Halo short film in '07, but when that project didn't pan out, he moved on to helming District 9 and sketching seemingly endless notebooks of Alien concept art.
Flash forward to the '18 Television Critics Association, where Showtime President and CEO David Nevins confirms that his network is still very much working on the adaptation:
"[Halo] is absolutely still in development, still moving forward and I’m encouraged by what we’ve seen so far… It’s still live action, and it will definitely satisfy the fans of Halo and I think also satisfy the drama audiences of Showtime.”
It's interesting that Nevins states that they've "seen" anything at all in regards to this project, so hopefully further details are coming soon (a writer/director/concept art/anything really). A sci-fi/action romp featuring Master Chief blasting a bunch of aliens doesn't exactly sound like something that would lend itself to weekly episodes, but we're here to see whatever Spielberg's been producing behind the scenes.
