Showtime has confirmed it is working a Halo tv series. Showtime-CEO David Nevins has confirmed the news through a press release.
The tv series will feature a total of 10 episodes. Not a lot is known about the story yet, but it will focus on the war between humanity and the Covenant in the 26th century. But given this short information we do know it will focus on the very first Halo game or even on one of the books that covers the story before we see Master Chief. In that case it makes the most sense to cover Halo: Harvest first contact.
The tv series will be produced by Kyle Killen and Rupert Wyatt. Killen is not a very big star yet, but we will have to give him the benefit of the doubt. Especially since Rupert Wyatt is also on the team. Wyatt has directed Rise of the Planter of the Apes, so we can expect a lot.
