James Gandolfini is among the crowded cast of this ensemble black comedy about war and international politics. When the American president and the British prime minister casually infer that they might like to wage a war in the Middle East, a minor British cabinet minister accidentally mentions the possibility of armed conflict in the near future to the press. This touches off a frantic international debate, with politicians and military leaders on both sides of the Atlantic enthusiastically lobbying for or against all-out war. This blisteringly funny satire is like a foul-mouthed combination of "The Office" and Dr. Strangelove. 106 minutes R.
