STV Studios labels, Tuesday's Child and Interstellar, have announced new entertainment commissions for Dave and Channel 4.0.

Interstellar's Battle in the Box (8 x 60') is a ground-breaking comedy reality game show for award-winning entertainment channel Dave and free streaming service UKTV Play. The series is based on a hit Korean format from Seoul-based format agency Something Special, and will be hosted by Jimmy Carr.

Battle in the Box will see pairs of comics and some of the nation’s favourite celebrities battle it out for pride, prizes, and most importantly, floorspace, in this comedy-entertainment and reality hybrid. The eight-episode series will comprise of four tense double bills which will see eight pairs spend 24 hours in a box.

When the clock starts, two celebrity teams will move into the completely empty box, divided by a moveable wall, with nothing but a toothbrush. Once inside, they will only have cameras and each other for company – no beds, tables, chairs, or home comforts. Over the course of the day and night, they will need to earn everything by winning a series of physical and mental challenges all set by the orchestrator of this chaos, Jimmy Carr. Winning a game means more space and luxuries for the lucky duo. But there’s a catch: more room for one team means less for the losers, as the box’s sliding wall forces them into an ever-smaller space. And with games set around the clock, the tide – and the wall – can turn at any time.

Executive producers are Jamie Ormerod and David Williams and the series producer is Tom Corrigan.

Elsewhere, Tuesday's Child has been commissioned to produce prank game, Bad Baby, for Channel 4's digital-first brand, Channel 4.0. The show will see host Chloe Burrows observe from the ‘control centre’ as unassuming young couples are thrown into the world of parenthood and required to perform a number of cringe-worthy tasks to soothe their foul-mouthed ‘bad baby’ in order to win a cash prize. Each episode, Chloe is joined by a guest prankster who plays the role of 'Bad Baby' - dialling up the mischief and causing chaos for the unsuspecting couples.

Bad Baby is a six-part series produced by Tuesday’s Child and the executive producer is Steph Harris with Will Brown as series producer.
