From the beginning of the sound era until he won his Oscar for The Informer John Ford turned in an interesting body of work. Some of his films are good, others less so. It seemed to me it took him a bit longer than some of his peers to master the technique of sound on film.
Case in point is this World War I naval story Seas Beneath. An interesting and fine war film, it's hampered a great deal by a rather unrealistic romance between the sister of a U-Boat commander Marion Lessing and George O'Brien the American captain of the mystery ship.
O'Brien is in command of the so-called mystery ship which has a pair of big guns camouflaged on board. The object is to look like a harmless American schooner and play decoy until the U-Boat comes in range and then cut loose. When the schooner puts into the Canary Islands for provisioning and to pick up any loose information, the Germans have the same thing in mind. In fact a female spy played by Mona Maris seduces young officer Steve Pendleton and finds out he's a lieutenant. Pendleton redeems himself in a most spectacular incident.
The battles at sea are staged very well. Surprising that other than star George O'Brien none of the known regulars from the Ford stock company are here. Walter C. Kelly plays the CPO of the ship and he's kind of a poor man's Victor McLaglen.
John Ford completists will like the film and it's all right, but nothing more.
