Seas Beneath is a 1931 American Pre-Code action film directed and produced by John Ford and starring George O'Brien and Marion Lessing.
[1] In the book, John Ford by Peter Bogdanovich, Ford was interviewed about his memories of directing the film, and he had the following to say about the experience, expressing his annoyance at Lessing being hired as a leading actress: That was a war story about a Q ship - some good stuff in it - but at the last moment, the head of the studio put a girl who'd never acted before in as the lead because he thought she spoke a few words of German - which she didn't.
We had a scene, I remember, in which the German submarine slips up alongside another submarine to refuel, and this girl comes out onto the bridge chewing gum!
That stuff was good and so was the battle stuff, but the story was bad; it was just a lot of hard work; and you couldn't do anything with that girl.
