Oprah Winfrey will produce a new drama about Martin Luther King, Jr and the US civil rights movement called Selma.

Winfrey's The Butler co-star, David Oyelowo, will play Dr King.

The film tells the story of a group of black marchers who attempt to walk from Selma, Alabama, to nearby Montgomery in order to gain the right to vote in 1965.

Winfrey will produce the film with Brad Pitt through his production company, Plan B.

Director Ava DuVernay told The Hollywood Reporter: ''It's a subject matter close to her heart. The producers are behind some of the most forward-thinking movies of last year and they are all coming together."
