Fallout is getting some more star power ahead of season 3. Prime Video announced Thursday that Emily Mortimer (The Newsroom, Love and Amazing), Manny Jacinto (The Good Place, The Acolyte), and Thomasin McKenzie (Jojo Rabbit, Last Night in Soho) will be joining the cast.

They’ll join Ella Purnell, Walton Goggins, Aaron Moten, and Kyle MacLachlan in the main cast. Aaron Paul was recently cast for season 3 as well. Production for the upcoming TV season begins in Los Angeles this month.

So far, Prime Video’s Fallout adaptation has been another successful case of a video game series making the jump to television, with the first season racking up over 100 million views as of October 2024. This initial run was nominated for 17 Emmys, including Outstanding Drama Series and Outstanding Lead Actor in a Drama Series for Goggins. The second season generally received positive reviews, although it was criticized for some circuitous storytelling. Season 3 was greenlit in May 2025 before the second season aired.

For those who haven’t watched the show, it follows Lucy (Purnell), a naive vault dweller who ventures into a post-apocalyptic Los Angeles in pursuit of her father (MacLachlan). Along the way, she meets The Ghoul (Goggins), a former Hollywood actor mutated into a near-immortal gunslinger. From here, Lucy crosses paths with the Brotherhood of Steel, a band of technofascist jerks.

These days, the Fallout series is being kept alive through an unlikely pair: the initially maligned live-service game Fallout 76 and Amazon’s TV show. Bethesda Softworks, the current stalwart of the video game franchise, has been working on The Elder Scrolls 6 for what feels like an eternity, with the next mainline Fallout game forced to wait in line. The situation at Bethesda seems to be yet another case of a AAA game suffering from a bloated development cycle driven by increased expectations around graphical fidelity.

With Bethesda’s owner Microsoft gearing up to conduct mass layoffs and studio closures, the future of Fallout is uncertain. Xbox CEO Asha Sharma has said she wants the company to speed up development on games in The Elder Scrolls and Fallout series, but it’s unclear what that would entail. It’s possible this would involve bolstering Bethesda with support studios. Even if that were to happen, it’s likely the next Fallout game is still many years away.
