Steven Spielberg's live-action Halo TV series is still in development. In 2013, during their Xbox One unveiling, Microsoft announced that they were working on a live-action Halo series, with legendary film director Steven Spielberg executive producing via his production company, Amblin Entertainment. The news came several years after Neill Blomkamp's planned Halo movie had fallen by the wayside, something that has turned Microsoft away from pursuing future video game movie adaptations. In this case, though, the TV series was part of a new initiative to bring original shows to Xbox consumers.
The series had been picked up by Showtime, and Spielberg was rumored to direct the series in addition to producing. After some time had passed, it was revealed that the show would launch in 2015 alongside 343 Industries' Halo 5: Guardians. However, when Microsoft shuttered their Entertainment Studios division in 2014, under Phil Spencer's new leadership, and thus canceled plans to develop original video programming for their Xbox systems, people believed that the live-action Halo series had also been canceled. Interestingly, though, that doesn't seem to be the case.
Microsoft Studios and 343 Industries, the studio in charge of the Halo brand, recently provided an update to AR12Gaming, stating that they are still working on the project alongside Showtime and Spielberg's Amblin Entertainment, though they didn't have any new information to share at this time.
“Progress on the Halo Television Series continues. We want to ensure we’re doing this the right way together with a team of creative partners (Steven Spielberg and Showtime) that can help us build the best Halo series that fans expect and deserve. We have no further details to share at this time."
Spielberg has been hard at work with his upcoming two movies - The Papers and Ready Player One - but it sounds like he's still working on bringing audiences the best version of Halo that he and his producing partners are capable of doing. Perhaps after finishing work on Ready Player One, an adaptation of Ernest Cline's sci-fi, video game novel of the same name, Spielberg will have reinvigorated his interest in pursuing the Halo series. Funnily enough, the acclaimed director managed to sneak in the Halo Assault Rifle into the movie, One, which viewers can spot in the first Ready Player One trailer.
Despite being one of the highest-selling and most beloved video game properties out there, the Halo franchise has yet to find success with movie and TV adaptations. Aside from the doomed Halo movie from the mid-2000s, the last instance in which Microsoft attempted to bring Halo to life in live-action was with the Halo: Nightfall digital series that launched alongside Halo: The Master Chief Collection in 2014, which was written by Prison Break creator Paul Scheuring and produced by Ridley Scott's company, Scott Free Productions. Hopefully, Spielberg's Halo TV series works out this time around, whenever it releases.
