Goofs

In the plane, Vivi has her scarf on in the long shots, but all the close-ups show her with her hair loose.

When Viv is lying by the lake she gets onto her knees and blows a whistle. In the next shot she is still lying down while blowing the whistle.

When the teenage Ya-Yas are going to Vivi's bedroom after the birthday party scene, they pass Buggy's room. When Vivi stops to watch Buggy, Teensy bumps into her coming up the stairs. There's a close up of Buggy, and then the camera cuts back to Vivi. Teensy comes up the stairs again and bumps into her.

When Lulu runs into Vivi's room, Vivi checks her temperature and picks her up. Lulu then vomits onto Vivi's nightdress, but in the next frame, the nightdress is clean.

In the plane scene (Siddalee's flashback, near the end), you see all the cars pull up to the field. In the car beside the one Vivi is driving, you see a girl jump out of the car twice.

The Ya Yas arrive at Teensie's aunt's house in Atlanta for the premiere of Gone with the Wind (1939) in December 1939 in a 1941 or 1942 Packard.

At one point, Sidda & her siblings are seen watching the Merrie Melodies cartoon called "Dough Ray Meow". This scene is set somewhere around the late '50s-early 60s; Heathcliff did not come out until the 1980s.

When teen Vivi dances with Jack at her birthday party, the band singer can clearly be seen mouthing lyrics during the instrumental part of the song.

Near the beginning of the film, there is a shot of the Belasco Theatre in New York, where Sidalee's play is about to start performances. The Main marquee and windows on the theatre display the marquee for her play. However, one of the marquees over the entrance has a general marquee that reads "See a Broadway show just for the fun of it!". The Shubert Organization (which owns the theatre) only uses these generic marquees in a theatre that is currently empty and no upcoming show is booked into it. This marquee would never appear on a theatre that is in previews/has a show about to open.

The invitation to Vivi's birthday party is for Friday, December 18, 1944. December 18, 1944, fell on a Monday.
