A deeply weird 1946 movie with Glenn Ford and Rita Hayworth. Netflix's AI thought I would like it slightly better than I did.
Ne'er-do-well smalltime gambler Johnny (Mr. Ford) is about to be mugged and probably killed in an Buenos Aires back alley, when he's saved by tungsten tycoon/casino owner Ballin Mundson (played by George Macready). I don't think a reason was given for Mundson to be on the scene; even less explicable is what happens next: he invites Johnny to his casino, and after some gay repartee, hires him to do some vaguely-described duties.
The relationship between Mundson and Johnny is tense, and it doesn't get any better when Mundson returns from a brief trip with a new wife: Gilda, played by Ms. Hayworth. Gilda and Johnny are hostile toward each other from the get-go, and, as it turns out, there's a very good reason for that… But that's enough plot description.
Let it be said that there's enough dysfunction in the triangular relationship between Johnny, Gilda, and Mundson to send a marriage therapist into a different line of work. Mundson's tungsten machinations turn out to be a source of dangerous intrigue as well. Rita Hayworth sings and dances. Everybody smokes and drinks way too much.
Oh, and the ending is … well, it's damned odd, given all the ominous foreshadowing.
