Castaway: Cambodia

 — All-Stars is the eighth season of Castaway and was produced on February 13, 2021.

The season borrowed elements from the CBS reality television competition Survivor. Hosted by Robert, it consisted of twenty-four returning competitors from the previous seven seasons of Castaway.

The three tribes, Angkor, Bayon and Ta Keo, were named after temples in Cambodia. When twenty competitors remained, Angkor was dissolved with the remaining competitors shuffled into two tribes of ten. A further swap when sixteen competitors occurred. When thirteen competitors remained, the tribes merged to the Tangkor tribe named by Jocelyne, a portmanteau of Ta Keo and Angkor. Joshua won the season over Nicholas and Greg in a 4-3-0 vote.

Notable twists include Exile Island returning from a one season hiatus and observing the rules introduced in Castaway: Millennials vs Gen-Z alongside Trial by Fire introduced in Castaway: One World.

Development and Casting
The season was announced after applications for Castaway: One World closed on January 26. Applicants consisted of previous contestants of the series and unlike the season the show is based on — Second Chance — the season will feature competitors from all phases of the game (pre-jury, jury, finalists and winners) the original intention for the season was to divide the contestants into two tribes of twelve, but after wanting to pay homage to the first four seasons having eight contestants on each tribe, Angkor was made a starting tribe with it's dissolution after three rounds.

Casting for the season proved difficult due to the increased interest from former players which led to Castaway: Redemption Island being created for a second group of returnees who were not selected for All-Stars. Jazzie who had played in David vs Goliath was due to compete as a member of Ta Keo but did not arrive on time, her spot was replaced by Will.
