The film
Behind the Lines is about Owen and Sassoon. It was based on a Booker Award-winning novel by Pat Barker. The film focuses on the psychiatric hospital at Craiglockhart. It is good. Incidentally, John, this is the poem that Fenton quotes in the NYRB article (on American art during the WWI period).
