Yo, Mista White! Aaron Paul is set to star in Fallout season 3.

According to Deadline , Paul has joined the cast in an undisclosed role, which reunites him with Westworld producers Jonathan Nolan and Lisa Joy. He starred as Caleb Nicholas in seasons 3 and 4 of the hit sci-fi show, which ended in 2022.

Back in 2024, Nolan let slip that Paul, who is a huge fan of the video game franchise, was hoping for a role in Fallout season 2 . The rumor was that he would play the leader of Caesar's Legion, a role that ultimately went to Macaulay Culkin. We don't know what role Paul will play next, though we do hope it's an entirely new one made for t he upcoming season's surprise location ...

Paul joins the newly promoted Annabel O'Hagan (Steph) and Dave Register (Chet), who will now be series regulars. No word yet as to whether Culkin's character will receive a promotion as well (following the, uh, in-show promotion his character receives), or if Kyle MacLachlan will return as a series regular following his character's, uh, demotion.

Aaron Paul posted the announcement to his personal Instagram account , with star Walton Goggins commenting, "That's my guy! I've got some Radaway waiting for you, Cowboy!!!"

Fallout received an early renewal for a third season back in May 2025, ahead of its December release date, with production on Fallout season 3 expected to kick off this month. The series has amassed over 100 million views across both seasons, making it Prime Video's most successful original show.

Fallout season 2 is streaming now on Prime Video. For more on what to watch, check out our guide to everything new on Prime Video in April .
