Khalid Abdalla is a British Egyptian actor and activist. He came to international prominence after starring in the 2006 Academy Award-nominated and BAFTA-winning film, United 93. Written and directed by Paul Greengrass, it chronicles events aboard United Airlines Flight 93, which was hijacked as part of the September 11 attacks. Abdalla played Ziad Jarrah, the pilot and leader of the four hijackers on board the flight. He starred as Amir in the film of The Kite Runner and acted with Matt Damon in Green Zone, his second film with director Paul Greengrass. Abdalla appears as himself in Jehane Noujaim's documentary on the ongoing Egyptian revolution, "The Square", which won the Audience Award at Sundance Festival in 2013.
Abdalla is on the board of the National Student Drama Festival. In 2011 Abdalla became one of the founding members of the Mosireen Collective in Cairo: a group of revolutionary filmmakers and activists dedicated to supporting citizen media across Egypt in the wake of Mubarak's fall. Three months after it began, Mosireen became the most watched non-profit YouTube channel in Egypt of all time, and in the whole world in January 2012.
