While FalloutSeason 2 was one of Amazon Prime Video's biggest 2025 releases, no one is discussing it now, which seems strange considering Season 1's popularity. Season 1 dropped on the streaming service in April 2024 and stars Ella Purnell, Xelia Mendes-Jones, Aaron Moten, Walton Goggins, Kyle MacLachlan, and Moisés Arias as a fascinating cast of characters navigating the aftermath of a nuclear apocalypse. Fallout Season 2 has thrilling new cast members, including Kumail Nanjiani and Macaulay Culkin, and the Season 2 premiere dropped on Dec. 16th, 2025.
