When Noxeema is reeling off titles of films made by Dorothy Dandridge, his/her favorite star, he/she mangles the title of Sun Valley Serenade, turning it into the meaningless Serenade Sun Valley. Noxeema also misquotes the order of filmography and omits several. These are not things the character, a hardcore Dandridge fan, should have done.
In the early scene where the girls are seated at a night club table with John Jacob Jingleheimer Schmidt (Robin Williams,) his hat does some amazing things. Between shots of Schmidt and the girls, his hat brim goes from just above his eyebrows to a point well above the hairline and continues to alternate for about six separate shots.
After Chi Chi checks to see if Sheriff Dollard is dead they take off in the car, prior to taking off in the car no shoe is present at the back of the vehicles driver side wheel, but when they show the vehicle driving off the shoe then shows at the back of the vehicles driver side wheel.
During the bar scene (at around 1h 28 mins) the shoe that Virgil picks up and inspects suddenly changes to a different shoe from one shot to the next. Most evident in the toe strap (more open, then flattened) and different wear patterns at the heel (just a few scratches, then a larger wear).
Toward the end of the movie, the girls are hiding in their hotel room. A young girl comes to the door and asks for Miss Vida and Auntie Noxi. Before she opens the door, there is nothing on the back side of the door except a hanging dress. Seconds later when she closes the door, Chi-Chi is hanging on the back of the door.
The "girls" are settled-in and relaxing in their pajamas, lingerie, and bunny slippers. Problem is, they were not carrying any baggage when they got their lift into town. Then, while they are still dressed this way, they look out the window to see their car being towed-in.
When they first enter the little town after their car breaks
down, they are led to a little room where they are to stay and Chi Chi runs to shut off the light that Carol Ann just turned on. The light alternately switches from off when the camera is on Chi Chi in the middle of the room, to on when the camera is on Noxeema and Vida and Carol Ann at the door.
When the three ladies are sitting at the kitchen table, gluing back together a little doll figurine that had broken, the doll appears repaired just as Vida says "putting someone else's needs before you own". Just a couple seconds later, the camera briefly cuts away to Chi Chi. When it cuts back to Noxeema as she says "It was step three" the doll is broken again.
The "Places for Homos" list that Sheriff Dollard first writes out on the hood of his cruiser (at 59:04) is different (re-written) when it's shown again just 3 minutes later in the flower shop (at 1:02:23).
When Sheriff Dollard turns on his lights and follows the girls, the cruiser has four square headlights (likely a Dodge Diplomat). But when Chi Chi turns to look behind the Cadillac, the cruiser has two large, round headlights. Then when they pull off the road, the cruiser is a 4-light Dodge again!
When Chi-chi joins the ladies at the table to announce that she is giving up her boyfriend, the glass of wine next to her changes from half full to empty several times, and the wine bottle label rotates.
When Vida and Noxeema first encounter Chi Chi on the stairs, she is wearing both of her gloves. When Vida sits next to her a second later, Chi Chi is wearing only one glove, and is holding the other in her hand.
When the girls arrive in Snydersville they decide to fix up the room they are staying in, when they get started Chi Chi has both shoes on, during the sequence Chi Chi begins to dance and at that time she has only one shoe on, but when they finished Chi Chi sits down and now has both shoes on again.
During the first drag competition when the girls are doing the wave in line, Vita is the first one, Noxeema is in the middle somewhere, and Chi-chi is near the end putting her on the far right end of the stage. In the next scene, Vita is near the middle, Noxeema is at the far right end, and chi-chi is dancing with Cappuccino Commotion on the left side of the stage.
On the movie poster, Vida, Noxeema and Chi-Chi are seen in a somewhat brand new blue Cadillac. But in the movie the Cadillac they drove in was yellow. Also on the movie poster, Chi-Chi is wearing a yellow and pink dress, but in the movie at the drag queen contest, Chi-Chi's dress was green and pink.
During the "Brick House" montage where the girls in the car are making hand gestures to the people in the train, you can clearly see that Patrick Swayze's character has his hands of the steering wheel for an extended amount of time, yet the car continues to drive straight - making it obvious that the girl's Cadillac is being pulled by a rig.
