As suggested above, the main interest of this was the view of the backstage planning and machinations that were necessary for the interview to occur. Billie Piper as Sam Macallister was shown as being a key element in this process but I felt that her character was over-emphatically represented as an ‘outsider’ to the usual BBC public-school characters. She spoke differently from them, had a rather spiky attitude and wore her ‘outsider’ status rather obviously and other elements in her life – a single (?) mother, her own mother’s support, her constant fighting against the hierarchy – were rather clumsily and obviously portrayed.
Anderson as Emily M was, characteristically quietly effective and Rufus Sewell as Andrew was excellent. He caught the sulky arrogance that Andrew invariably seems to convey in public. But seeing him in the bath and then a rear nude shot as he saw his interview was petty ab surd and quite unnecessary. It added nothing to the drama and was completely gratuitous.
But I thought that when the interview started, the fact that we only saw a few parts of it – and not all the most notorious/memorable parts either (pizza/Woking etc etc) - was a smart decision. The interest in the drama was not in what Prince A said but in the lead up to and the fall-out from the interview. These better-known aspects only came out in the aftermath.
