His life was as compelling and enigmatic as his art, set against the dramatic wartime locations that inspired him. This film brings to life this unique and still grossly undervalued British artist caught in the crossfire of war 80 years ago, whose legacy largely sank without trace, until now.

The film asks what it is to be a war artist, featuring Ai Weiwei, Alan Bennett, Grayson Perry and many more, to be released in his 80th anniversary year.
