Showtime has announced the main cast for the long awaited Halo TV series. It was previously revealed that Pablo Schreiber had been cast as the iconic Master Chief character, which was back in April. Since then, fans have been waiting to get more information about the series, fearing for the worse. Thankfully, Showtime has some promising news. We are now one step closer to seeing the Halo series finally become a reality after waiting for years.

Natascha McElhone, Bokeem Woodbine, Shabana Azmi, Bentley Kalu, Natasha Culzac, and Kate Kennedy will join Pablo Schreiber in the Halo TV series. McElhone, is arguably best-known for her work on Showtime's Californication. The actress is all set to play two parts in the series, including Dr. Catherine Halsey, who is "the brilliant, conflicted and inscrutable creator of the Spartan supersoldiers." She is also playing Cortana, "the most advanced AI in human history." Cortana is also potentially the key to the survival of the human race.

Bokeem Woodbine is set to play Soren-066, who is "a morally complex privateer at the fringes of human civilization whose fate will bring him into conflict with his former military masters and his old friend, the Master Chief." Shabana Azmi will play Admiral Margaret Parangosky, the head of the Office of Naval Intelligence in Showtime's Halo series. In addition to the aforementioned characters, the show will introduce three brand-new characters. Bentley Kalu is one of the new characters, Spartan Vannak-134, "a cybernetically augmented supersoldier conscripted at childhood who serves as the defacto deputy to the Master Chief."

Natasha Culzac is playing another new character in the Halo series, Spartan Riz-028. The character is described as "focused, professional and deadly, cybernetically enhanced killing machine." Rounding out the newcomers is Kate Kennedy who stars as Spartan Kai-125, "an all-new courageous, curious and deadly Spartan supersoldier." The cast joins the previously announced Yerin Ha, who is playing a 16-year-old from the Outer Colonies named Quan Ah. Ah will join Master Chief at a "fateful time" for them both. Story details for the highly anticipated series are being kept under wraps for the time being, but it looks like production is preparing to start, so we should get a lot more information soon.

Showtime's live-action Halo series sees Kyle Killen and Steven Kane serve as co-showrunners and executive producers. The new series is executive produced by Darryl Frank and Justin Falvey and is based on the world famous Xbox video game series of the same name. The Showtimes series was first announced back in 2013 with Steven Spielberg and Neill Blomkamp attached. However, things did not end up working out in the end and spent five long years in development. Thankfully, Showtime made the announcement in 2018 that everything was still moving forward, which brings us to where we are now. Deadline was the first to announce the latest cast additions for the Halo series.
