Survivor 51 launches 'Open Era' on CBS: all past twists back in play

CBS's Survivor 51 premieres 23 September, opening what host Jeff Probst calls the "Open Era": any twist from the show's 50-season history can resurface at any time, in any order, without warning. Probst announced the concept during the Survivor 50 finale. The cast of 21 first-time players, aged 24–49, has no returning contestants. (The Hollywood Reporter, 26 August 2026)
