The Green Prince is such an extraordinary story that one is tempted to think it is fiction. Based on Mosab Hassan Yousef’s memoir, Son of Hamas, it is a story of two men, spy and handler, whom history insists must be adversaries. That they could reach a point of trust or friendship seems absurd. Embroidering a tangled web of intrigue, terror, and betrayal, director Nadav Schirman builds superb tension throughout a surprisingly emotional journey.
