'One to one' with John Lennon and Yoko Ono

BBC Talking Movies presenter Tom Brook explores the just released IMAX film One to One: John and Yoko, which covers the 18-month period when the couple first arrived in New York City in 1971 and lived in the Greenwich Village neighbourhood.

The documentary makes use of restored concert footage, never-before-seen home movies and recordings of telephone conversations.

For Tom, a long-time Lennon fan, watching the film was an emotional experience. He covered the slaying of the former Beatle at the Dakota apartment building for BBC News on 8 December 1980.
