* AdaptationDisplacement: The novel on which it's based, ''Me and The Arch Kook Petulia'', is remembered mainly because of this movie (and the odd fact that its author, John Haase, was a [[HeAlsoDid dentist who wrote fiction on the side]].)
* HollywoodPudgy: Several lines of dialogue reveal that Archie's son Mike is supposed to have weight issues, but when we see him he looks quite thin, even taking into account that he was said to have lost 11 pounds after his parents divorced.
* RetroactiveRecognition: Several later familiar character actors have uncredited bit parts. It was the film debut for Howard Hesseman and Austin Pendleton, and the second film for René Auberjonois.
* SlowPacedBeginning: Actually, the issue is that the opening scene at the fundraising gala is kind of disorienting. It tosses almost all the film's main characters at us in quick succession and sets up the basic premise in short bursts of conversation. Once Archie and Petulia leave and go to the hotel, things settle down and it's easier to get into the film.
