...But what catches you off balance is the casting of Matthew Macfadyen as Charlie. That's right, the same Matthew Macfadyen whose boyish charms sparked up Spooks and made Keira Knightley's heart flutter as Mr Darcy in Pride And Prejudice. It's a daring piece of casting that not only fulfils the intention of scuppering the demonised stereotype of the paedophile but also reveals Macfadyen, who turns in an entirely convincing performance, as an actor of unexpected range.

It's a brave performer who plays so defiantly against type but Macfadyen is reticent in accepting praise. 'I'm not interested in looking after my image,' he says. 'I suppose there might be a hostile reaction to the film because it's such an emotive subject. But it's not my job to worry about that.'
