Wow does this film have some odd casting. While practically everyone aboard the submarine speaks American style English, Charles Laughton and Cary Grant are cast in two of the leading roles despite their accents. This sort of casting happened relatively frequently in older Hollywood films, but it is confusing to the viewer.
The film begins with Charles Laughton married to Tallulah Bankhead. It seems their friends have been talking about Tallulah's behaviors. Common knowledge is that she is cheating on poor old Charlie, though it turns out this is not true. Laughten is exceptionally paranoid and delights in playing like the slighted husband by starting these rumors himself! Later, he accuses one of his officers (Cary Grant) of committing adultery with Tallulah and delights in destroying Grant's career--even though the man did nothing inappropriate.
In response to Laughton's cruelty, Tallulah runs off and is rescued by dashing young Gary Cooper as she runs amok in an Arabian town. He falls for her but she rebuffs his advances because she's a decent woman. However, she does kiss him and soon makes her escape back home. Soon afterward, Cooper reports to her home--it seems he's the officer who's replacing Grant. However, seeing that his nice commanding officer is married to a woman that let him kiss her, he assumed (incorrectly) that Talullah is a cheat--not understanding that Laughton is certifiably insane.
Talullah comes on board the submarine that will be sailing later that night in order to try to explain herself to Cooper. However, when Laughton sees she's on board, he orders the boat to sail immediately, as he sees an insane chance to punish the two "lovers"--leading to a very exciting final portion of the film. In fact, from then on, the film is at its best. The final moments aboard the ship were exceptionally well done and Laughton's final scene quite memorable. Since this film was made "Pre-Production Code", the scene is particularly graphic and exciting.
Overall, although the film starts a bit slowly, it's a dandy film that combines a naval film with a psychological drama. I must admit that the final five minutes or so of the film seemed a tad awkward, but what proceeded was exciting and it's a heck of a good film.
