When Sammy makes Annelle a cherry Coke, the glass changes after he pours the Coke, but before he throws the cherry into it. The level of liquid also momentarily drops. Not to mention that when he is pouring the soda into the glass, the soda is clear, not coke.
The movie takes place in the fictional "Chinquapin Parish" in the state of Louisiana. Several times characters refer to the parish as "the county" and even "Chinquapin County." Louisiana has no counties, only parishes.
At Shelby's wedding reception, Nancy Beth sports two very different hair styles. Early on when she's dancing, it's smoothed down, but later when they are eating cake inside the house, it's quite big and curly.
When Ouiser and Owen arrive at the Easter Egg Hunt at the end of the movie, Ouiser is wearing cream color high heel shoes. At the very end when everyone is waving and following the vehicle backing out of the park to take Annelle to the hospital, Ouiser is wearing brown socks with white lace and grungy looking tennis shoes.
At the Christmas Holiday Festival, Truvy and Annelle are working the concession stand. Truvy hands a box of food to a woman standing next to Shelby. The woman hands Truvy a bill and has her arm out-stretched for the change. Truvy hands the money to Annelle. The shot changes, Annelle appears to give the change to the woman. It then goes back to the original shot the arm is still outstretched for the change.
When Shelby spills her orange juice in the beauty shop, the glass loses about half its juice. However, when Annell starts cleaning it up, there appears to be at least a couple of glasses of juice on the floor.
When Ouiser is confronting Annelle outside Truvy's before the wedding, the shots move back and forth between Ouiser and Annelle. With each shot back to Annelle, the eggs are in different order. The yellow egg on Annelle's right in the upper right corner of the top tray comes and goes.
The wedding scene opens with a closeup of Ouiser sitting in the pew looking bored. She is clearly toward the center of the pew, with a woman on her left and a black gentleman in the row directly behind her. In the very next shot, she is sitting at the end of the pew (aisle seat) and the same black gentleman is two rows behind her.
When Shelby is at home dressing Jack Jr. for Halloween, we see her lift him and scream out in pain. She cannot seem to stand up and crawls backwards to call for help. The next shot shows the refrigerator door wide open, and food bubbling all over the stove. How could the refrigerator door be left wide open when Shelby cannot even stand up, and she is also crawling to the phone?
When Clairee, Truvy and Annelle are in church, they are sitting in back of a family whose pew looks full. Ouiser walks in and winks at Owen. We see the family again, and the pew is still looking full with the mother, son and daughter sitting very close together. In the next shot Ouiser is standing next to the pew and suddenly there's a big space between the sister and the brother, where Ouiser sits.
While Ouiser is 'grilling' Annelle near the trunk of the car behind Truvy's hair salon, Annelle is holding a couple of flats of colored eggs for the church, the eggs change colors many times from shot to shot.
When Shelby and Jackson are getting in their wedding getaway car, one of the condom balloons got closed in Shelby's door right by her head. Then in the next shot when the car is pulling away, that condom balloon is back on the outside of the car again.
Before the wedding, all of the girls are in Truvy's, talking. Clairee is sitting in front of a stack of Easter eggs. Notice how the colors and placement of the eggs change almost every time the camera pans to Clairee.
When Sally Field pins a corsage on Julia Roberts after the wedding, they are almost the same height, but Julia Roberts is almost 6 inches taller than Sally Field. No shoes could make them the same height. Then, the next shot has them walking to the door together and now the difference in height appears correct.
While the ladies are in the cemetery after Shelby's funeral, Truvy gives M'Lynn a compact. M'Lynn opens it up to check her appearance but in the following scenes, the compact goes from open to close and back to open again as M'Lynn gets angry over Shelby's death.
In the final scene in the park next to the canal, when Annelle
begins to have labor pains and is taken from the park in Spud's SUV, shadows indicate that it is early to mid-morning. In the next shot, as a helicopter camera follows the SUV and motorcycle through the city streets, the shadows indicate that it was shot in the late afternoon.
At the Christmas party, when Drum is announcing Shelby's
pregnancy, the wide camera shot shows Shelby and Jackson standing side-by-side, and the very next tighter shot shows them leaning against one another, hugging.
