'Darkest Hour' looks at Churchill during WWII

Writer Anthony McCarten on the set of "Darkest Hour."

During Winston Churchill’s first few weeks in office, allied nations continued to fall to Nazi troops. The threat of Hitler’s forces invading the UK loomed, and German forces surrounded 300,000 British troops at Dunkirk. Churchill faced a critical choice: make peace or fight.
