In September 1971, two years after the Beatles split up, John Lennon, dispirited and disillusioned with life in England, escaped across the Atlantic to New York City. He was tired of the constant scrutiny and criticism at home, and hated the venomous press hounding him and Yoko Ono. He dreamt of starting a peaceful new life in a city he'd come to love. Instead what followed was more like a rollercoaster ride: a tempestuous period in his relationship, a battle against the US immigration authorities, and a famous wild spell: the 'lost weekend'. Michael Epstein's fascinating film, featuring previously unseen archive footage and unprecedentedly candid interviews with key figures including Yoko Ono, charts this little-known period of Lennon's life - the years leading up to his untimely death.
