Back in the 1970s, Richard Nixon sicced J. Edgar Hoover's FBI on Beatle John Lennon, who was singing about peace, preaching against the Vietnam War and getting all kinds of people to listen. He was followed, monitored and threatened with deportation. This documentary from David Leaf and John Scheinfeld doesn't pretend to be all-inclusive. Its laser focus is on the arrogant persecution of Lennon and his wife, Yoko Ono, and their insistence on fighting back. The film is loaded with testimony and talking heads. But it's Lennon, in remarkable footage released by Ono, who makes a case that seems aimed right at Bushworld. Lennon's spirit, like his music, shines through this movie like a beacon. Powerful stuff.
