A hit documentary about Al Jazeera television drew sharp reactions this week in a rare screening in the Arab world where the popular channel is often banned. "Control Room" was a surprise hit at U.S. box offices this year with its fly-on-the-wall look at the Arabic channel and its coverage of the U.S.-led war in Iraq. But the response of Arab viewers to the film, which has yet to be distributed in any Arab country, was one of anger and unease at the Dubai International Film Festival at a screening watched by Hollywood star Morgan Freeman, Andrew Hammond reports for Reuters.
