AN EastEnders legend and Strictly star lead the lineup for Jimmy Carr's brand new comedy game show.
The show, called Battle in the Box, sees two pairs of celebrities go head-to-head in a series of mental and physical challenges.
Set to air next year on UKTV's Dave channel, each star is locked in an empty box for 24 hours - with only just a toothbrush and toilet.
Comedian Jimmy Carr will present the series, as the contestants battle for floor space - but the more rounds they lose, the smaller their box becomes.
And The Sun can exclusively reveal former EastEnders actor Joe Swash has signed up for the show.
