Author Lawrence Wright & former FBI agent Ali Soufan on 'The Looming Tower'

‘The Looming Tower’ on Hulu follows FBI agent Ali Soufan as he tries to prevent an Al Qaeda attack on U.S. soil. The real Soufan says watching an actor play him has been weird, but could have an important payoff: teaching people what led to 9/11 and preventing another attack. Soufan and ‘The Looming Tower’ author Lawrence Wright tell us how they adapted the complicated story for TV.
