Will Arnett Joins Kristen Stewart in NASA Drama ‘The Challenger’

Will Arnett has joined “The Challenger,” the Prime Video limited series in which Kristen Stewart plays astronaut Sally Ride, with the comedy veteran cast as NASA flight chief George Abbey. The Amblin Television drama traces the 1986 space shuttle disaster, the investigation that followed, and Ride’s run as the first American woman in space.

The casting turns a project that has sat quietly since 2024 into something closer to a working production. It also drops a recognizable comic actor into one of the grimmest chapters in American spaceflight, opposite a film star who has never carried a television series.

Arnett Trades Comedy for NASA’s Control Room

For most viewers, Arnett is a voice and a smirk. He played the venal Gob Bluth on “Arrested Development,” voiced the title character across six seasons of Netflix’s “BoJack Horseman,” improvised his way through “Murderville,” and growled as LEGO Batman. The register he reaches for by instinct is deadpan and absurd.

George Abbey gives him almost none of that to work with. The role is a fixer and a gatekeeper, a man who decided careers behind closed doors at the Johnson Space Center. Arnett has stepped sideways into drama before, co-creating and starring in the addiction story “Flaked,” and more recently joining the ensemble of Taylor Sheridan’s Western the Yellowstone spin-off “The Madison” led by Kurt Russell and Michelle Pfeiffer. “The Challenger” asks him to anchor scenes built on bureaucratic pressure rather than punchlines.

That is the first piece of the wager. Casting against type can deepen a character or expose an actor; it rarely lands in the middle.

Who George Abbey Was at NASA

Abbey ran flight crew operations during the years that built the shuttle program’s reputation, and he is the reason Ride flew when she did. As NASA’s director of flight crew operations through the early shuttle era, he chose which astronauts were assigned to which missions, a quiet power that made him one of the most consequential figures inside the agency without ever strapping into a cockpit.

In 1983 he put Ride on the crew of STS-7. The choice was not automatic. Chris Kraft, then running the Johnson Space Center, favored another candidate from the same astronaut intake; Abbey backed Ride and defended the decision. Months later she became the first American woman to reach orbit.

Abbey kept rising after that, eventually serving as director of the Johnson Space Center, and he held real influence over the human spaceflight program into the 2000s. He died in March 2024 at 91, which means the series is dramatizing a man whose decisions are still recent history to many of the engineers and astronauts now telling these stories. Arnett is playing a real institutional power broker, not a composite.

Stewart’s First Major Television Role

Stewart anchors the project, and for her the move carries its own stakes. This is her first major television role, a deliberate pivot for an actor who spent the decade after “Twilight” rebuilding her reputation in art-house cinema. She earned an Academy Award nomination for “Spencer,” took a César for “Clouds of Sils Maria,” and worked with directors like Olivier Assayas and Kelly Reichardt.

She is not only starring. Stewart produces “The Challenger” through her Nevermind Pictures banner alongside Dylan Meyer and Maggie McLean, which gives her creative skin in the outcome rather than a paycheck role. That follows a year in which she moved behind the camera for her directorial debut and kept stacking projects on both sides of it.

A Crowded Slate

The TV move arrives while Stewart’s other commitments shift around her. Her Panos Cosmatos vampire film “Flesh of the Gods,” set up at A24 with Wagner Moura, hit a snag this year when Stewart said the thriller was short on financing. A limited series with Amblin and Prime Video behind it is a steadier bet than an independent feature still chasing money, which may explain part of its appeal.

Playing a Public Icon

Ride is a demanding part. She was a physicist, a reluctant celebrity, and a private person whose relationship with Tam O’Shaughnessy became public only after her death from pancreatic cancer in 2012. NASA’s own profile of the astronaut notes that Ride later sat on the boards that investigated both shuttle losses, Challenger and Columbia, the only person to do so. Stewart has to play the symbol and the guarded woman underneath it.

The Book and the Astronaut Class Behind the Story

The series adapts Meredith E. Bagby’s 2023 book “The New Guys,” which tells the story of NASA’s 1978 astronaut intake. That group was selected from roughly 8,000 applicants and broke the all-white, all-male mold of the Mercury and Apollo eras. It included the first American women, the first Black and Asian American astronauts, and several names that the Challenger story would later turn tragic.

The official logline keeps the focus on Ride while signaling the disaster at the heart of it:

The events leading up to the Challenger disaster, the investigation that followed, and Sally Ride’s groundbreaking journey as the first American woman in space.

Several members of that 1978 class give the drama its weight:

• Sally Ride, the physicist who flew on STS-7 in 1983 and became a household name.
• Judith Resnik, an electrical engineer and the second American woman in space, who died aboard Challenger in 1986.
• Ellison Onizuka, the first Asian American astronaut, also killed on the Challenger flight.
• Guion Bluford, the first African American to reach space, later in 1983.

That overlap is what makes the source material more than a biopic. The same class that put a woman in orbit lost two of its own on the launch the series is named for, a tension Bagby drew out in interviews about how the 1978 group reshaped NASA.

The Pedigree Behind ‘The Challenger’

The names attached to the production explain why Prime Video is spending on this. Maggie Cohn, who created the series and runs the writers’ room, built her reputation on fact-based prestige drama. James Hawes, directing, came off the spy hit “Slow Horses.” Kyra Sedgwick’s Big Swing Productions developed Bagby’s book for the screen, and Amblin Television, the Steven Spielberg company, gives it studio muscle.

Cohn’s last two credits both turned messy real-world events into character-driven television, which is exactly the assignment here. Pair that with a streamer that has been hunting for awards-season titles and the bet starts to look less like a gamble and more like a calculated swing at prestige.

Where the Bet Could Wobble

The Challenger story is well-trodden ground. A Netflix documentary revisited the accident in 2024, and the disaster has anchored films and specials for decades. A scripted series has to justify why audiences should sit with it again, which puts pressure on the Ride angle to feel fresh rather than dutiful.

Then there is the casting math. Arnett against type and Stewart untested on the long-form TV grind are two unknowns stacked in the lead roles, and the show’s appeal rests on both landing. Audiences forgiving of a comic actor in a serious part are not guaranteed, and a film star’s screen presence does not always translate to eight hours of episodic work.

Prime Video has not set a premiere date, and no episode count has been confirmed. The project was first announced with Stewart attached in mid-2024, and Arnett’s arrival in June 2026 is the clearest sign yet that it is moving toward cameras. Until a release window lands, “The Challenger” is a strong cast and a strong book waiting on a date.
