In casting this season, Probst stated, "We want a cast that represents all types of players, spanning all the eras. An array of people who have slept bled this ever-changing game design for the last 25 years. Because, really,
Survivor 50 is a representation of everyone who has ever played and the fans who've been with us for the entire time." In August 2024, Probst stated that the casting team started with a list of 200 previous players and had narrowed it down to 100 by that point in time. When asked by Dalton Ross in October 2024 about players potentially in the casting pool taking offers for shows on other networks including
Australian Survivor and
The Traitors, Probst said "We've had many players call us and say, 'I only want to do
Survivor again.' That also makes an impression on us. We take note of that loyalty, and we appreciate it. But we definitely don't demand it." By February 2025, the list was whittled down to 50. Following the cast reveal on May 28, 2025, Probst said "Casting
Survivor 50 was kind of like casting the ultimate all-time movie. And you think about all the actors who are alive today that you could put in that movie, but there is only so many roles, and we wanted Fifty to be a little taste of everything. 'Cause...we've done
Heroes vs. Villains, and
Game Changers, and
Fans vs. Favorites, and
Winners. We wanted to taste every flavor, every type personality, all the eras." The first 22 (out of 24) players in the cast were officially revealed by Probst on the May 28, 2025, edition of
CBS Mornings. The final two cast members, both from
Survivor 49 which had yet to air, would not be revealed until after that season's finale on December 17. Five-time
Survivor player

Survivor 44. Despite the hypothetical change in policy, Jesse Tannenbaum (casting director for all of CBS's reality shows) stated, "Well, from my perspective, nothing's changed. I've always, in the back of my mind, felt we needed more diversity on these shows...I'm still shooting for having a really diverse cast because I think everybody needs to be represented." ==Marketing==
