“The Bibi Files” started with a sudden leak that turned into a deluge. A source contacted documentarian Alex Gibney out of the blue and offered access to video recordings of police interrogations of Prime Minister Benjamin Netanyahu, his wife, Sara, son Yair and many others – some 1,000 hours of footage in all. Gibney, who produces, and director Alexis Bloom have turned the footage from Netanyahu’s ongoing corruption case into a provocative documentary that is banned in Israel due to privacy laws. Still, Israelis are finding ways to see it via pirated links, and the film has the propitious timing to be releasing just as Netanyahu takes the stand this week in his trial.
