Who looks like who in W

Josh Brolin is ... George W Bush, a pampered boor, oppressed by his dad and overshadowed by his younger brother. What is he to do? Find God, quit booze and start a war of dubious legality? Don't misunderestimate him, or he just might surprise you Photograph: Evan Vucci/AP

James Cromwell is ... George Bush Sr. History may remember him as a peevish, preppy type who race-baited his way to the White House and then proceeded to throw up into the lap of the Japanese PM. Turns out that he is really a wise, sad, good-hearted old saint who shakes his head sorrowfully at the antics of his eldest son. Who knew? Photograph: Max Nash/AP

Toby Jones is ... Karl Rove. The man dubbed 'Bush's brain' pulled the strings on two disputed presidential elections and generally toiled to shield his master's shortcomings from the world at large. Just don't ask him to rap ... Photograph: Stefan Zaklin/EPA

Richard Dreyfuss is ... Dick Cheney (aka Vice), the cantankerous power behind the throne, endlessly lobbying for a war on Iraq (reconstruction courtesy of Halliburton). Seriously now: would you go on a hunting trip with this man? Photograph: Manny Ceneta/EPA

Thandie Newton is ... Condoleezza Rice. First she was national security adviser, and then she was secretary of state. In both incarnations she maintained the same blend of steely ambition and Uriah Heep-ish supplication. Sometimes known to let her hair down (as Hurricane Katrina battered New Orleans, she took herself off to see Spamalot) Photograph: Justin Sullivan/Getty

Scott Glenn is ... Donald Rumsfeld, the amateur wrestling champ turned cheerful architect of 'Operation Iraqi Freedom'. He knows about the knowns, and he knows that there are unknowns that we may not know about and he also knows that 'stuff happens' from time to time. Clearly this is a man with his head screwed on Photograph: Stephen Jaffe/AFP

Elizabeth Banks is ... Laura Bush, the sweet Texan librarian and one-time LBJ supporter who hitches her caboose to a rightwing Republican not known for his highbrow literary tastes. Here's a woman who's guaranteed to turn a man off his drink Photograph: Ron Sachs/EPA

Jeffrey Wright is ... General Colin Powell. He's a respected military man, a former chairman of the joint chiefs of staff and a pristine emblem of American integrity. So what is he doing raving about yellowcake and anthrax to the UN Security Council? Was it the 'Vice' what set him up? Photograph: Dave Gadd/Sportsphoto Ltd/Allstar

Ioan Gruffudd is ... Tony Blair. What we need at this stage is a hero to head this crew off at the pass, a voice of reason to soothe the sabre-rattling, and a man who will stand up for international law. What we need is Tony Blair ... isn't it? Photograph: Mario Tama/AFP
