Oldies will be pit against youngsters in the new series of The Island with Bear Grylls, a report claims.
The Channel 4 show maroons participants on a remote island to test whether they have the skills they need to survive.
And its upcoming fourth series will apparently feature an experimental new twist: an age divide.
According to The Sun, this year's castaways will be split in to two groups - the young and the old.
The show will examine which ages cope best with the tough conditions, although the rival sides are likely to merge later in the series.
"This extreme social experiment will answer whether it’s youthful vigour or wise experience that keeps you alive," a source said.
The Island first hit our screens in 2014, with fourteen men left to fend for themselves without modern luxuries.
Accusations of sexism led the second series to feature two different islands - one with men and one with women.
Last year's run was the first to feature both genders together. The males and females initially arrived on opposite sides of the same island, without knowing the other group was there.
A celebrity version of the show was also launched last year, in aid of Stand Up To Cancer.
The Island will return to Channel 4 later this year.
