Which British artist is the subject of an acclaimed film by Mike Leigh?

Mr. Turner is a 2014 internationally co-produced biographical drama film on the last twenty-five years of the life and career of painter J. M. W. Turner (1775–1851). Written and directed by Mike Leigh, the film stars Timothy Spall in the title role with Dorothy Atkinson, Paul Jesson, Marion Bailey, Lesley Manville and Martin Savage. It premiered in competition for the Palme d'Or at the 2014 Cannes Film Festival, where Spall won the award for Best Actor and cinematographer Dick Pope received a special jury prize for the film's cinematography.

The film was critically acclaimed and received four nominations each at the 87th Academy Awards and 68th British Academy Film Awards.

Describing Turner as "a great artist: a radical, revolutionary painter", writer/director Leigh explained, "I felt there was scope for a film examining the tension between this very mortal, flawed individual, and the epic work, the spiritual way he had of distilling the world".
