Dennis Quaid will play Bill Clinton, Julianne Moore will play Hillary Clinton, and Frost/Nixon star Michael Sheen will once again play Tony Blair in The Special Relationship, a forthcoming HBO film about the global leaders, Variety and other outlets report. The film, which has yet to be greenlit, specifically centers on Bill Clinton’s interactions with Blair around when the British Prime Minister first took office. It is the anticipated directing debut of screenwriter-playwright Peter Morgan (Frost/Nixon), who previously wrote The Queen and The Deal, both of which featured Sheen as Blair. Quaid played a character loosely based on George W. Bush in American Dreamz.
