The "Fallout" TV series, as mentioned by Aaron Moten, the actor portraying Brotherhood of Steel hopeful Maximus, is planned to run for 5 to 6 seasons. Speaking at Comic Con Liverpool, Moten revealed that the show's endpoint has been set since he signed on for the series, aiming for a Season 5 or Season 6 conclusion. He emphasized that the development of the characters would be a gradual process throughout the series.
The continuation of the show up to its planned endpoint largely depends on its ongoing success. Given the explosive popularity of Season 1 and the high anticipation for Season 2, "Fallout" appears to have a strong chance of reaching its intended finale. Notably, production for Season 2 has recently wrapped, with actors Walton Goggins and Ella Purnell celebrating the milestone on social media.
