Continuity mistake: During the scene that Truvy is styling Shelby's hair for the wedding, we see Truvy start taking the rollers out of the left side of Shelby's hair. The camera then goes to another character and when it comes back Truvy is again taking the rollers out of the left side of Shelby's hair while the rollers on the right side are now out. (00:18:30)
Continuity mistake: In the scene where the women are putting the Easter eggs into the trunk, the first shot shows Annelle placing cartons into an almost full trunk. It is also shown that there are many more on the roof of the car. When Ouiser shows up, Annelle continues to place them in the trunk. There was no more possible room in the trunk to hold all of the cartons that were on the roof, and the ones that were there disappear.
Continuity mistake: In the scene at Shelby's reception when the whole crowd of guests are dancing to "On the Bayou," at one point everyone gathers around a particular couple who are burning up the dance floor. If you look at the crowd gathered as the shots change from different angles, Dolly Parton and Olympia Dukakis, among others, are in different places each time.
Continuity mistake: When Julia Roberts has a diabetic attack in Truvy's shop, she is given a glass of orange juice, and she shakes so much that she spills about half the glass. But when Daryl Hannah grabs a towel and goes to clean it up, there's at least 2 glasses' worth of juice on the floor. (00:24:50)
Revealing mistake: In the scene where Shelby goes into kidney failure and is passed out on the stairs of her home, Jackson runs over to her and grabs her up. Looking closely, you can see Shelby hold her head up. If she were really unconscious, her head would fall back as Jackson sweeps her up into his arms.
Continuity mistake: In the scene at Truvy's before Shelby's wedding, Shirley MacLaine shows up with her dog, which she ties to the tree in a standard single knot (like that's going to hold a St. Bernard). When Drum shoots the firecrackers into the trees at the birds, you see the dog become agitated and break the leash, which is no longer tied, but secured around the tree by slipping the length of leash through the handle part.
Continuity mistake: In the last scene at the easter egg hunt Shirley Mclaine comes in with brown high heel shoes on. When she creeps up behind the tree to sit with Jack she has no shoes on and when she is running after the truck taking Darryl to the hospital she has tennis shoes and white ankle socks.
Continuity mistake: In the scene where the women are putting the eggs into the car and Ouiser walks over to Annelle and begins to converse with her, she is holding a carton of the eggs. The two front corners of the eggs keep changing colors as the shots keep changing from Ouiser and Annelle speaking.
