Continuity mistake: When Sidda is lying on the couch, in the house where she has been taken by the women, as she is talking on the phone to her fiance, she is lying on a scarf behind her head in close-up. After it cuts away then back on her, there are two scarves behind her head, but after another cut away it's back to only one scarf again.
Other mistake: The age difference between Ya-Ya's and Sidda is off. If you assume that Sidda is in her late 30's, then it is impossible for her mother to have attended the Gone with the Wind premiere as a tween, been a teenager during WW2 and been in her early twenties when she had Sidda, her oldest child. Sidda should really be about a decade older. If Sidda were the youngest child, it would make sense.
Continuity mistake: In the beginning when the four young girls are sitting around the campfire. Vivi takes a drink of chocolate from the chalice, then passes it to the next girl. In the next shot, chocolate stains in the corner of her lips are visible that weren't there before, and she didn't take another drink.
Continuity mistake: When Sidda wakes up after being kidnapped by the Ya-Ya's, she takes a bloody mary to the front porch and sits in a deck chair. During the flashback to Sidda's childhood, the Ya-Ya's and their kids are at the beach. Vivi blows the whistle around her friend's neck to get the kids' attention. In the first shot, she is on her knees. The shot suddenly changes and she is still blowing the whistle but is now sitting down.
