Filmmakers record a revolution in Oscar doc ‘The Square’

Director Jehane Noujaim, producer Karim Amer and their team shouldered cameras on the streets of Cairo as Egypt's 2011 uprising unfolded. The famous "18 days" -- centered on central Cairo's Tahrir Square -- led to the downfall of a dictator, Hosni Mubarak. Noujaim and Amer sat down last week with PBS NewsHour's Margaret Warner in Washington to discuss their film "The Square."
