In December 2020, John Lennon will have been dead for 40 years. Yet his art still speaks to millions of people. This film establishes Lennon as an American artist. It is, essentially, a classic immigrant tale: Lennon and Ono left London in 1971 in search of freedom, both artistic and personal. With unprecedented and exclusive cooperation from Yoko Ono, access to never-before-seen material from the Lennon archives and conversations with those closest to him -- Ono, Elton John, the photographer Bob Gruen, Ringo Starr -- AMERICAN MASTERS tells John Lennon's story as it has never been told before.
