This week is being devoted by Channel 4 to the weird and sometimes disturbing world of \u201cfake news\u201d. They are starting things off with a panel show pilot, which may sound dreary to some, but there are some interesting aspects to it, such as the fact it is a rare pre-watershed comedy. Stephen Mangan acts as host as he and his guests (Richard Osman, Katherine Ryan, Jon Richardson and Richard Ayoade) try to make sense of fake news, alternative facts and post-truth politics. The show has already made a bit of stir before even airing, with a fake story concerning Ryan having some botched plastic surgery was reported as fact by some news outlets. The Fake News Show is on Channel 4 at 20.00.
