In January of 2011, Egyptians took to Cairo's Tahrir Square to lead what became a revolution. One experienced documentary filmmaker was there, and she kept filming for more than two years, shooting away during several unexpected transformations of the Arab Spring. Jehane Noujaim, who grew up in Cairo, documented the fall of dictator Hosni Mubarak in 2011, the election of the Muslim Brotherhood candidate Mohammed Morsi, and then his removal from power last summer. Her documentary, The Square, is now getting Oscar buzz. Kim Masters, host of The Business, KCRW's weekly program on the movie industry, sat down with Noujaim and actor-and-activist Khalid Abdalla, who appears in the movie.
