Made during the pre-Ealing comedy era, when the studio was turning out a slew of propagandist dramas with a documentary feel (others included WENT THE DAY WELL? (1942), and THE FOREMAN WENT TO France (also 1942)), SAN DEMETRIO London tells the story of a British merchant ship blown up in 1940. The crew spend some time marooned in a life-boat, but eventually return to the stricken ship and manage to patrol it back to safety in the United Kingdom.
Co-directed by Charles Frend and Robert Hamer, the film has its roots in documentary, ranging from the use of stock footage to the way in which it examines the lives of ordinary sailors coping with extraordinary situations. The plight of Greaser John Boyle (Mervyn Johns) is sensitively handled, as he quite literally works himself to death and passes away at sea, dreaming of the nylon stockings he has bought for his wife as a present. He is given a funeral with full naval honors. Likewise Messboy John Jamieson's (Gordon Jackson's) transition from callow youth into mature deckhand is cleverly depicted, as some of his suggestions - initially dismissed as impractical by Chief Engineer Pollard (Walter Fitzgerald) turn out to be inspired, helping the crew survive their ordeal.
The film as a whole extols the value of community, of human beings setting aside their regional and national differences and learning how to pull together in times of extreme stress. "Yank" Preston (played by the Canadian Robert Beatty), an American passing for a Canadian, begins the film as something of a rebel, preferring the bottle to the responsibility of hard work, but soon proves to be an invaluable member of the crew. It is he who provides the Bible so that Boyle can be given an appropriate send-off to the other world. Even though the bombing of British cities had largely ceased by 1943 - the time of the film's release - it was important that people on the Home Front bonded together to aid the war effort, and SAN DEMETRIO London fulfilled an important purpose in communicating this message.
As befits a studio relying mostly on performances and directorial cunning rather than elaborate special effects, the film concentrates on characterization rather than incident. Some of the action sequences might seem a little rudimentary now - especially with the use of back-projections - but we have to remember that the film was produced under difficult conditions with a limited budget. Directors Frend and Hamer make skillful use of such constraints to produce a film that is at once surprisingly touching as well as stirring in its impact.
