Ninth Doctor Christopher Eccleston has been cast as former Beatle John Lennon in a new BBC drama – opposite former Torchwood star and Aliens of London guest Naoko Mori (Toshiko Sato) as Yoko Ono.

Lennon Naked charts his transition from “Beatle John” to enduring and enigmatic icon. It covers a period of wildly fluctuating fortunes from 1967-71; a time of worldwide adulation at one extreme, a combination of frustration and despair at the other.

Meeting Yoko Ono was the catalyst for this new era and the film explores the development of their extraordinary relationship. Together they experimented with both the musical and artistic avant garde but in doing so become outsiders.

It looks at their growing disillusionment with Britain and what caused John to abandon the UK to start a new life in America. A process that included John harnessing the power of radical Primal Scream psychotherapy to lay the ghosts of his past and go on to record arguably the most powerful solo work of his career.

Currently filming in London, Lennon Naked is written by Robert Jones and also stars Key cast also include Christopher Fairbank as Freddie Lennon, Naoko Mori as Yoko Ono, Claudie Blakley as Cynthia Lennon, Rory Kinnear as Brian Epstein, Allan Corduner at Art Janov, Michael Colgan as Derek Taylor and Andrew Scott as Paul McCartney.
