“Could I offer one piece of serious advice?…Start thinking now about you want your legacy to be.” Having made peace with The Queen, Tony Blair (Michael Sheen once more) now contends with President Bill and First Lady Hillary Clinton (Dennis Quaid and Hope Davis respectively) in this brief teaser for Richard Loncraine’s The Special Relationship, written by Peter Morgan. (This is the fifth Morgan/Sheen collaboration after The Deal, The Queen, Frost/Nixon, and The Damned United.) With this, Treme, The Pacific, Song of Ice and Fire, and Boardwalk Empire, the reasons for re-subscribing to HBO seem to be mounting.
