It’s a chat show like no other. 24 Hours With… provides an innovative twist on the traditional chat show format as celebrity and interviewer spend an intense 24 hours locked in a room together.

The guests leave their mobile phones and PR advisers at the door, and host Jamie Campbell can ask them whatever he likes.

Each 24-minute show tells the story of their 24 hours in the hot seat, with a digital clock at the bottom of the screen marking the passing of the day.

24 Hours With… is the absolute opposite of a typical celebrity interview. There’s no hype – just real chat and the chance to really get to know a star.

Campbell won’t be holding back. He’s a provocative journalist and documentary maker with a disarmingly honest approach and a natural gift for the killer question. Stir in the sensibility of a stand-up comedian, and you have the perfect ingredients for a chat show like no other.

What emerges from this intense encounter is the absolute opposite of a typical celebrity interview: intimate conversation, rather than chat, and the chance to really get to know a star.
