A new topical news format sees celeb panelists locked away in a media-free zone for three days. So far so good. Anything that gets Frank Skinner off the streets, even briefly, gets my vote.

But then, worse luck, they're let out to answer questions from quiz-master David Mitchell. Can they spot real news stories from fakes and should we care?

Other guests this week include the very funny ­Reginald D Hunter and Victoria Coren. Fingers crossed that Katie Price and Peter Andre can both be enticed to enter this media-free bubble and that a junior researcher "accidentally" loses the key.

This could possibly be the most deranged variety show you'll ever see, the only place on earth where you can watch Christopher Biggins pretending to be Boris Johnson, and Jerry Hall impersonating Katie Price. If that doesn't draw you in, how about Joe Pasquale as Lady Ga-Ga? Or Ulrika Jonsson as David Beckham? No? Surely Vanessa Feltz masquerading as James May is irresistible. As is Eamonn Holmes as Elvis Presley. And David Gest as Elton John. Les Dennis as Gary Barlow... The list goes on, and just gets odder. The All Star Impressions Show could be completely awful or it could be enjoyably barmy. It certainly has a very good pedigree, being co-produced by Steve Coogan's and Vic Reeves and Bob Mortimer's production companies. And it has a certain surreal gloss that could be quite winning. Harry Hill will make a guest appearance, though we don't know whether he will reprise the Morrissey impression that won him Celebrity Stars in Their Eyes all those years ago.
