It seems that a BBC documentary series can't be made these days without a celebrity to promote it. Recently we've had Sam Neill with "Space" and this series presented by comedy veteran John Cleese. What qualifies these people escapes me, since they appear to have no real expertise at all, just a curiosity like the viewing audience. If you think John Cleese is God (like some people do), or even if you just like him (and I realise how popular the cult "Monty Python" was/is in the US), you'll be immediately interested in any series he gets involved in. Personally, I think that John Cleese is about as funny in this series as he was in those supermarket commercials (to viewers outside the UK, that isn't very funny). He does tend to be a bit OTT at times, but the premise of the series has its merits. It was certainly an unusual idea to dedicate a show to the human face, and you learn plenty of things you'd never have known, and could easily have lived without knowing. Mr Cleese isn't the only celeb appearing in the show. Liz Hurley makes an appearance as an example of the human face at its most beautiful, and we learn the mathematical formula that makes her so incredibly gorgeous (shame I can't remember what it is).
