... there was Hell Below with Robert Montgomery and Walter Huston. Made in 1933, the film was about submarine warfare in World War I. It's credited with setting most of the standard plot and action elements of submarine movies to follow, from Run Silent, Run Deep to, yes, Das Boot. I've never seen it myself but would like to. Alas, it does not appear to be available on DVD. An old thirties flick I'd love to see that's not yet on DVD? What else is new?
