Whether it's unfinished business, new enemies, or justice waiting to be served, lead star Alan Ritchson always delivers. Us Weekly breaks down what we know so far about the cast and more. Is 'Reacher' Getting a Season 4? Buckle up Reacher fans, because the show was given the green light for a fourth season in October 2024. "Windows everywhere beware," Ritchson captioned an Instagram post at the time, next to a photo of him shattering the glass on a car window with his fist. "Reacher Season 4 is official. What are you gonna give me if I spill the beans on the book?" Viewers have enjoyed the previous action-packed episodes so it came as no surprise that the renewal for the Prime Video hit was confirmed even before the show's third season aired in February 2025. The same happened for season 3, getting approval before season 2 premiered in December 2023. Sonya Cassidy and Alan Ritchson.
