A new film by Oscar-winning documentarian Alex Gibney My Trip to Al-Qaeda has been debuted at the Tribeca Film Festival, which takes viewers from Cairo to London on a search for the cultural and historical roots of al-Qaeda and some of its motives behind its attack on the United States. My Trip to Al-Qaeda, follows US journalist Lawrence Wright's worldwide exploration of the historical context of what formed and radicalized al Qaeda and its leader, Osama bin Laden. Adapted from Wright's 2007 one-man play that was based on his Pulitzer Prize-winning book The Looming Tower: al Qaeda and the Road to 9/11, it shifts between Wright's storytelling on stage and real-life interviews with Wright's sources.
