Walter tells Catherine on their wedding night that he was planning on running a charter service with his boat--but it then it was later destroyed. What do you suppose he and Catherine ended up doing after the war?
They always could get another boat. I do not think he taught or drank again. Do you think they ended happy or was it just being caught up in the moment? Well it was a feel good movie and one of C.G.'S LAST FILMS that Walk Don't Run was a dud.
I've sometimes speculated that, without a boat (or even while waiting for an opportunity to purchase a new one), Walter actually worked for Houghton throughout the remainder of the war (although not in as hazardous a position). He and Houghton were actually friends (all manipulations aside), and Walter now had more than himself to care about. After the war Houghton would return to his old job as a harbor master, and Walter and Catherine would set up housekeeping (plus a charter service) not too far away.
Given Walter's education (plus Catherine's), I suspect his charter service would be much sought after by research groups, universities and the like. One could almost imagine Walter rubbing shoulders with Cousteau in later years (with Jacques-Yves naturally charmed by Walter's Gallic wife). Catherine would, in fact, be instrumental in acquiring high-end clients for her husband. All in all a pleasant arrangement.
A delightful scenario, I'm sure.. I do wish they had at least shown them getting safely into the submarine however, and getting bedded for the evening.. a minimal post script is a nice touch.
I tend to agree. A lot still could've happened in the next few minutes. But then one is afterwards free to contemplate just how romantic one's inclinations could be . . . even if one were newly married . . . while on board a HMS (or RAN, or whatever) submarine. At the very least I suspect there'd be a great deal of hand-holding, and doubtless the Captain could lay his hands on some sort of beverage to toast the happy (and, more importantly, still alive) couple.
In reality the sub was sunk and the survivors sat out the war on a deserted, un-inhabitable island where they were forced to eat the children. Rumor has it that Anne was bitter and tough!
