Fallout season 3 adds Emily Mortimer, Manny Jacinto and Thomasin McKenzie

Prime Video has added Emily Mortimer, Manny Jacinto and Thomasin McKenzie to the main cast of Fallout’s third season. They join Ella Purnell, Walton Goggins, Aaron Moten and Kyle MacLachlan; Aaron Paul was recently cast as well. Production for the upcoming season begins in Los Angeles this month.

The series has been a strong performer for Prime Video: the first season surpassed 100 million views as of October 2024 and earned 17 Emmy nominations, including Outstanding Drama Series and a lead-actor nod for Goggins. The second season drew generally positive reviews but faced criticism for some circuitous storytelling.

Season 3 was greenlit in May 2025, before the second season aired. For new viewers, the show follows Lucy (Purnell), a naive vault dweller who leaves her vault for post-apocalyptic Los Angeles in search of her father (MacLachlan). Along the way she meets The Ghoul (Goggins), a mutated former actor turned near-immortal gunslinger, and crosses paths with the Brotherhood of Steel, portrayed as a band of technofascist jerks.
