Halo TV series: Everything we know so far

Though the Halo TV series started development all the way back in 2015, Master Chief's journey to a slightly different type of screen has not been an easy one. The sci-fi series was originally slated to be released on Showtime,  but since then, Paramount+ has taken the reigns, with Steven Spielberg's Amblin Television producing it.

Aside from that and some casting details, there isn't a whole lot we know right now. A trailer was released at The Game Awards last year, and while it did feature iconic elements such as a slightly weird looking Thunderhawk, High Charity, as well as Chief himself, it didn't reveal much about the plot beyond that the series is likely set around the events of the first three games.

It looks like the series might also delve into John's backstory and time in the Spartan training programme as a child, though we won't know for such until its release some time this year, or when more details arrive. Still, here's everything we currently know about the Halo TV series, including cast members, leaked images, and production details.

Here's the Halo TV series trailer from The Game Awards

Though it doesn't reveal all that much, it gives us our first look at the visual style of the series, characters like Dr. Catherine Halsey, and a pretty cool looking version of the Covenant holy city, High Charity. The trailer also has some dialogue from Halsey, presumably talking about Master Chief.

Though it doesn't give much away, the images of a child in the trailer, and Halsey's dialogue about her hopes for Chief, imply the series is likely to also focus on John's backstory as part of the Spartan training programme. The trailer also gives us a look at Master Chief, himself, and he looks on point.

And the Halo TV series teaser trailer

It's not much, but here's the first few seconds of footage from the Halo series. Master Chief has some gnarly scars, and that armor? That armor's looking pretty good.

Images from the Halo TV series have leaked

The Halo TV series has been in production since late 2020—long enough for some early cut of a trailer or production footage to be out in the wild and on Twitter. There's actually more to glean from these leaked stills than from the super short teaser trailer above.

Is Master Chief in the Halo TV series?

Yes. Yes he is. He's been confirmed at every opportunity, and we know who's playing him. Actor Pablo Schreiber has been cast as Master Chief. You may remember a younger Schreiber from his role as dockworker Nick Sobotka in season 2 of The Wire, or from some more recent shows and movies: American Gods, Skyscraper, Orange Is the New Black. According to IMDB, he's nearly 6'5″ tall.

Who's in the Halo TV series cast?

After Covid-19 delays and the resulting schedule changes, the Halo TV series has recast Cortana, its blue-hued AI. Natascha McElhone, originally cast as both Cortana and Dr. Catherine Halsey “the brilliant, conflicted and inscrutable creator of the Spartan supersoldiers”. Now, McElhone will still play Dr. Halsey but the role of Cortana is being picked up by Jen Taylor who has often played the same role in Halo games. It's not known at this point whether Taylor will appear in the show as Cortana, or simply provide the voice for a CGI character.

Additionally, Bokeem Woodbine will portray Soren-006, “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.” Admiral Margaret Parangosky, the head of the Office of Naval Intelligence, is played by Shabana Azmi.

We have the names of three Spartans, new to Halo with this series: “British actor Kalu will play Spartan Vannak-134, a cybernetically augmented supersoldier conscripted at childhood who serves as the defacto deputy to the Master Chief. British actress Culzac will star in the role of Spartan Riz-028 – a focused, professional and deadly, cybernetically enhanced killing machine. Kennedy stars as Spartan Kai-125, an all-new courageous, curious and deadly Spartan supersoldier. Yerin Ha was previously announced playing the new character Kwan Ha, a shrewd, audacious 16-year-old from the Outer Colonies who meets Master Chief at a fateful time for them both.”

What kind of story will the Halo TV series tell?

Story details are locked down, but Levine affirmed it as a new story “incredibly respectful of the canon” utilizing the franchise’s framework of the war with the Covenant and the eponymous Halo space stations. That’s further reinforced by this official post by 343 head of transmedia Kiki Wolfkill, who explained that the series will try to strike a balance between fan expectations and presenting something new.

“As we think about what it means to bring videogame franchises to movie or TV—the biggest challenge can often be finding the right balance between moments fans have already experienced and moments that have yet to be experienced through a different medium, perspective, or creative lens,” Wolfkill wrote. “We are excited to navigate these creative waters to bring you something that is both respectful of what you already know and love, but also new and surprising and enthralling.”

When in the Halo timeline might it take place? The war with the Covenant boasts several points of interest for a TV series. A possible strong angle could cover Chief’s origins, his conscription into the Spartan program (which would include an appearance of the titular planet from 2010’s Halo: Reach), and his eventual first contact with the Covenant, all of which would comprise a useful backdrop for plenty on-camera opportunities to show off John-117’s face in various stages of grizzled determination. An adaptation of Halo novel Fall of Reach would make sense—but if you're trying to bring in the Halo rings and tell a new story, that seems unlikely.

The Halo TV series is moving from Showtime to Paramount+

Showtime parent company ViacomCBS has decided to move Halo from Showtime to Paramount+, its upcoming streaming service, as reported by Deadline. Paramount+ will be ViacomCBS's replacement for CBS All Access, which is mostly known for hosting Star Trek: Discovery and Star Trek: Picard.

ViacomCBS chief creative officer David Nevins said that they “were on the hunt for signature shows beyond the Star Trek franchise on CBS All Access,” and after seeing some early footage from the series, Halo was a good fit. “It could be a defining show for a newish service that’s got all firepower of an entertainment corporation behind it,” he said.

For the people making the Halo series, it doesn't seem like much will change; it's still being overseen by Showtime executives. But it will matter to those of us who hope to watch it—Paramount+ and Showtime will remain separate premium subscriptions.

How many episodes will there be? 

Showtime’s initial order consisted of 10 hour-long episodes, a common season length for big-budget prestige TV series these days. That order has since been dropped to nine episodes. Showtime hopes Halo’s influential lineage will deliver the network’s “most ambitious series ever.” No pressure.

“[Halo] is futuristic space-based science fiction,” elaborated President David Nevins at the TCA conference. “It’s not fantasy. I think there's been one iconic franchise in my opinion in the history of television in that category and that's Star Trek. It was a long time to get the script where we felt we had something really interesting and felt like it belonged on Showtime in terms of its character depth. It’s going to be a big show.”

Who’s part of the production?

Steven Spielberg’s Amblin Entertainment is one of the bigger studios handling production duties. It’s yet unknown if the acclaimed filmmaker will personally have a role, but it appears Showtime’s project is a continuation of a concept Spielberg was set to executive produce back in 2013. Considering Spielberg’s background and enduring interest in science-fiction—being no stranger to the nostalgic pull of games—there’s a fair chance of spotting his name in the credits roll.

Developer 343 Industries (and Microsoft, by extension) is also involved in some direct capacity. Hopefully that's good news, and not the first step down a path towards another Assassin's Creed or Tomb Raider. 343’s responsibilities could simply entail making sure the series feels authentically Halo, leaving the TV pros to do their work.

Who is writing and directing the Halo TV show?

Kyle Killen was initially tapped as writer and showrunner. Killen’s most recent work, the largely panned Mind Games, failed to anchor an audience past its first and only season. His earlier and more fruitful endeavors included Fox’s Lone Star and NBC’s Awake, both sharing the same fate and lasting only one season. While Killen is relatively unblooded in the deep sci-fi genre, his recurring interest in theming a protagonist around facing plural realities could serve as an intriguing foundation for exploring the supernatural aspects of Halo’s far-reaching universe.

On a TCA tour, Levine explained Killen’s selection over more experienced writers was a deliberate one, saying, “We made a conscious decision to hire a writer not known for sci-fi and not known for big battle movies or anything. Because that's already baked into the Halo franchise and we will service that. But we also want to ensure that we get underneath the formidable armor of the Spartans.”

Steven Kane (whose production credits include American Dad! and The Last Ship) has been attached as co-showrunner. Killen has now left the project, and Kane will apparently be leaving after the first season.

Originally director Rupert Wyatt was going to be part of the project, but he exited the show in December. Now the series has a new lead director and executive producer in Otto Bathurst, who most recently directed the 2018 Robin Hood, and the first episode of Black Mirror (you know, the one with the pig).
