Filming for the third season of Amazon’s acclaimed Fallout show is expected to begin this month, and ahead of that, we’ve just got our first bit of casting news. Actor Aaron Paul has joined the cast of Fallout, alongside returning faces Ella Purnell and Walton Goggins.
Paul is known to many for his lead role in Breaking Bad, where he played meth cook Jesse Pinkman. Due to this character’s relationship with his former chemistry teacher Walter White, along with various lines in the show – including Jesse’s proclamation “Yeah, science!” – many now hope Paul will play a scientist in Fallout, though his role in the upcoming season remains a mystery for now.
More recently, Paul voiced Robert Robertson in AdHoc’s brilliant superhero workplace comedy, Dispatch. He also starred in the final season of Westworld, where he worked alongside Fallout’s executive producers Jonathan Nolan and Lisa Joy.
In addition, Annabel O’Hagan and Dave Register have been upped to series regulars for Fallout’s third season (via Variety). O’Hagan has played Vault 33 resident Stephanie “Steph” Harper since the show’s debut, and more of her character’s backstory was revealed over the course of season two. Register has similarly been part of Amazon’s Fallout since its first season, playing vault dweller Chet.
