Q&A with filmmaker Nadav Schirman.

This real-life thriller tells the story of one of Israel’s most prized intelligence sources: the son of top Hamas leader Sheikh Hassan Youssef, Mosab Hassan Youssef. For over a decade Mosab—code name: “The Green Prince”—was the number one source for the Shin Bet, Israel’s secret security service. Recruited at 17, he spied for his former enemy in the heart of his father’s organization. His Shin Bet handler, Gonen Ben Yitzhak, risked everything—including treason—to save him. The special bond between Mosab and Gonen made for one of the most unlikely but effective partnerships in the history of Israeli intelligence. The Green Prince is a gripping account of terror, betrayal, impossible choices—and a friendship that defies all boundaries.
