Continuity mistake: Near the end of the film, as Bette Midler, Diane Keaton and Goldie Hawn sing the song "You Don't Own Me," watch Goldie's shoes. For the first portion of the song, which takes place inside, she is wearing spiked-heel shoes with multiple straps. Then, as they dance through the doors onto the street, she is wearing shoes with a single strap and a much thicker heel.
Continuity mistake: When Elise, Annie and Brenda decide to make their own first wives club, Elise's glass of wine is almost empty, but when they throw their rings in the glass, it is almost full.
Continuity mistake: At the big dinner party they have look out for the man with black hair, gray suit with a turtle neck. He appears in back to back to back scenes - one second he's walking across the room the next he is dancing and a mere second later he's outside smoking. Either he has a twin or he gets around quick.
Continuity mistake: When they all are sitting down after the funeral, they order drinks. When the drinks arrive Goldie's drink is put down twice. Once when you are looking at her and once when you are looking from behind her.
Continuity mistake: At the end of the movie when the women are alone in the hall and singing, they are lip-singing to their recorded version. It's clearly the voices of the 3 women, but the music is out of sync with their lips.
Continuity mistake: When they are talking about getting revenge on their ex-husbands, Bette stands up and starts talking. She puts her hands on her hips. Then in the next shot, they're not on her hips, but in the shot after that there they are again, back on her hips.
Continuity mistake: At the start of the movie, Cynthia hands the maid some letters. Here Cynthia is holding a glass. When she goes out to the balcony she is holding a cigarette as well as a glass.
Continuity mistake: The three women do parts of their "You Don't Own Me" act at two different points in the movie, both times supposedly doing the choreography they had worked out for Cynthia's birthday party, 25 years earlier. But the two instances differ in what Goldie Hawn and Bette Midler do right after the "Ba-ba-ba-ba-ba-ba." The first time, they raise their hands over their heads. The second time, at the very end of the movie, they bend at the knees and put their hands together directly in front of Diane Keaton.
Continuity mistake: When the three ladies are trying to sneak out of Morty's house Annie has glasses on. In the next shot when they are about to climb into the window cleaning contraption she doesn't have glasses on. Next shot they are back on again.
