I'm not entirely sure how he manages it, but Martin Sheen, playing Prime Minister Tony Blair, damn near steals the show. And considering the magnitude of Mirren's performance, that is certainly saying something. Sheen's Tony Blair is a guy caught in a tricky situation. On the one hand, he is responsible for leading the country, but on the other, he stills take council from the Queen (a bizarre notion for us across the Pond, since when does our president ever take advice?). He's a modernizer, and as such clashes with the Queen's idea of things, but at the same time..."she's, you know, the Queen" he says. As leader, he has to walk a fine line, between what the people want and what is right both morally and politically.
