Good news Halo fans, the Halo television series will feature Spartan soldier John-117, aka. Master Chief. Master Chief is pretty much the face of the Halo series (also often the helmeted face of Microsoft's Xbox gaming console) , and likely the only name non-fans would know from the Halo gaming franchise. However, it seems that the series, confirmed to be coming to Showtime earlier this Summer, will be an original story not from the games, books, or comics yet will be "respectful of the canon".
Details about the series came from Showtime president and CEO David Nevins, who also said of the show:
"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 Halo tv series was initially announced back in 2013, so yes it has been a long time coming. It is planned to be a 10-episode series, which will be written and run by Kyle Killen, of which Nevins noted:
"We made a conscious decision to hire a writer not known for sci-fi and not known for big battle movies, because that's already baked into the Halo franchise and we will service that, but we also wanted to ensure that we were getting beneath the formidable armor of the Spartans and really getting inside the team drama so it felt like it belonged on Showtime," Levine added. "As David said, our hopes and dreams are that it will have enormous appeal to Halo fans and will also appeal to Showtime drama fans."
The show has not yet begun production, but is expected to land in 2020. We'll see how that goes.
