I saw a review of the pilot they did in front of an audience in December and it gave a good idea how the different presenters fit into the show.
Jimmy Carr: He's the main host, he introduces the show with topical humour on the week's news and he does John Stewart-like interviews with authors and whatnot.
David Mitchell: He chairs a debate/discussion with a panel of experts on the topic and uses this as an opportunity to go on one of his trademark rants.
Charlie Brooker: He does a Newswipe-like segment on a story from the week, and in the pilot this led into David Mitchell's segment with Charlie sitting on the panel. I'm not sure if Brooker is going to set up Mitchell's segment every week or it that was just a once-off.
Lauren Laverne: She interacts with the audience and asks for their opinions as well as reading messages on twitter.
At the end of the episode they all sit around a table discussing the next day's newspaper headlines.
Basically, it seems like it's going to be the Alternative Election Night minus the election. I'll watch it for Brooker and Mitchell, but I'm not sure if Jimmy Carr is up to the task of being the British John Stewart. But then again, John Stewart might not have appeared to be up to the task of being John Stewart until he tried it.
