Should play Gordon Brown

He may not look exactly like him, but when did that ever stop actors playing world leaders? We had Frank Langella and Anthony Hopkins as Nixon, Forest Whitaker as Idi Amin (the only visual similarity was their skin colour), James Cromwell as George Bush Sr and Helen Mirren doesn't really look like the Queen at all! I think the now-greying, middled-aged Rowan would be an inspired choice to play the dour Scottish PM, but in a satire/comedy rather than a serious biopic or factual drama. In fact I believe Brown was recently dubbed Mr Bean in one of the House of Commons slanging matches, perhaps a references to his apparent lack of people skills?
