Douglas Booth, the actor who starred in a BBC biopic of Boy George, has been lined up to appear in a film about A Single Man author Christopher Isherwood.

Booth, a 17-year-old Burberry model, played the Culture Club singer in Worried About The Boy and will play the role of a street cleaner who Isherwood has a brief relationship with.

Doctor Who actor Matt Smith, 27, is to play Isherwood in the film, titled Christopher And His Kind.

It began shooting in Belfast this week and tells the story of the authot as a young man who escapes his suffocating mother to move to Berlin in the 1930s.

The film is based on Isherwood’s memoirs of the same name.

Smith became the 11th Doctor Who last year, succeeding David Tennant.
