The Belly of an Architect (1987)

Brian Denehy is both nouns in The Belly of an Architect (1987). He's in Rome to work, which is the architecture stuff, but he's also coming to terms with the fact that he's dying of stomach cancer, which, obviously, is the belly--and what a gut this dirty bum carries around with him so majestically. The movie begins on a train where Denehy impregnates his wife Chloe Webb, who shows off some hoot and then bum as she fools around on Denehy and he peeks in through a keyhole later in the film. Yes, this is not a happy marriage. But Denehy is no cuckold. This architect builds a mighty erection when he hammers the full-frontal beauty of Stefania Casini in an arty but hot seduction. By the end of the movie, Denehy's baby is born, his marriage and career are in ruins, but he got to stick it to Stefania. That's an even trade-off.
