Other mistake: When Cry-Baby's gang arrives and Uncle Belvedere is taking a bath, Snare-Drum and Suzie Q ask Hatchet to make the monster face and Snare-Drum starts to run, but then he appears on the other side of Suzie Q and runs after her.
Other mistake: When Carl has received the Nassau bank account number from the drug dealer on the phone, afterward you see him typing in "Rita Miller" on the computer. If you watch closely, his left hand pinky never touches the "A" key on the keyboard, yet the "A" in Rita comes up just fine and out of sync with the clicking sounds of the keyboard.
Other mistake: Right after Julie is born and they're taking her away, the nurse is opening the door. Then they change over to the mother, then back to the baby, and the nurse is just opening the door again.
Other mistake: After the drivers enter their cars at the Daytona 500 at the end, there is a shot where Russ Wheeler's #18 Hardee's car is in the inside lane and mid-pack a row ahead of Cole's car on the outside. In the overhead shot as they get the "start your engines" command and the shot immediately following, you see Cole on the inside and Russ on the outside of the last row. This is compounded because they show Russ looking to his right and Cole to his left at each other indicating that they have reversed sides again. Also, Russ starting mid-pack would not be feasible and back of the pack unlikely since they said he won the pole. Even with the Duels races setting up the lineup, the front row qualifiers still stay the same at Daytona. Russ could be at the back if he made changes to his car (which Cole did). Not sure if either of those rules were different in 1993. Along the line of the Duels, the plot seems to imply it is Cole's first time back in the car and he is nervous. However, he would have run in practice and his duel race already by the start of the 500.
Other mistake: As the hotel manager is going over table manners with Vivian, when he picks up the salad fork he says salad forks have 3 tines, but when he puts that fork back on the table you can see it has 4.
Other mistake: Near the end of the film, Charlotte and her mother (Mrs. Flax) are having a blazing row. Mrs Flax calls Charlotte 'the town tramp', and Charlotte retaliates by telling her that the town already has one. This results in Charlotte receiving a huge slap. This slap would leave her cheek as red as a tomato, but as the scene continues, there isn't a mark on her face. A tad unrealistic?.
