This week on The Jonathan Ross Show, pulses will be racing as Harry Potter hero Daniel Radcliffe talks about the transition from child star to adult actor for his new film The Woman in Black. Mighty Boosh star Noel Fielding will be chatting about life as a comedian - and possibly why he insists in putting his brother in every TV show he does (it's OK, Noel, you're not Ron Howard). And one of the world's best known natural history film maker, Sir David Attenborough, will be discussing his amazing career and setting the record straight following recent allegations of misleading viewers, after it emerged that some aspects of his TV show Frozen Planet were filmed from a Zoo. There will also be music from ''R&B legend'' Seal as he performs his new single Backstabbers.
