Other mistake: According to his driver's license, Clarence's birthday is on July 30, 1965. However, he attended a triple feature on his birthday, which appears to be set during the winter months.
Continuity mistake: In the scene where Clarence is cleaning Alabama's wounds outside the airport (after she gets beaten up by and subsequently kills her would-be hitman), a large gaping cut seen on the left side of her face in one scene is gone in the next and does not reappear.
Visible crew/equipment: In the scene where we see Elliot talking to Lee, while Lee is driving in his Porsche, in the view from right in front of him, you can see the reflection in his sunglasses, of the trailer pulling the car and the equipment. There also is an outline of two crew members.
Continuity mistake: After the rollercoaster scene, it shows Elliot very sick. The vomit on his sweater is sometimes there, and sometimes not.
Continuity mistake: In the scene where Clarence Whirly is killing the pimp Drexel, he fires 7 shots out of his gun. The gun he is holding only holds 6 rounds.
Continuity mistake: In the rollercoaster scene, at the beginning, Dick Ritchie's face in the background keeps switching from happy to terrified.
Other mistake: When Clarence and Alabama meet in the movie, the scene from "Street Fighter" is initially seen at the beginning of the movie, the next scene they show of the film takes place at the end. (00:05:44)
Continuity mistake: When Tom Sizemore is listening to Clarence threatening Elliot in the elevator with his headphones the plug for the headphones changes from being on his left ear to his right and then back again. The same thing then happens to Chris Penn a few seconds later.
Revealing mistake: When Alabama sets fire to Virgil's head and you see him stumble out of the bathroom, his head is greatly disfigured and larger, indicating the fire protective mask.
Continuity mistake: During the rollercoaster scene the person sitting directly behind Alabama keeps changing from a woman with long black hair to a man with short brown hair.
Continuity mistake: When Alabama, Dick and Clarence are in the car driving to the drug deal, Alabama slaps Dick with her make-up powder, leaving white powder on his cheek and nose. Dick then turns to Clarence and the powder is gone.
Factual error: The final scene shows the sun setting over the ocean. They settle in Cancun, Mexico. Cancun is on the east coast. The sun sets in the west.
Suggested correction: We know that they wanted to settle in Cancun, but that doesn't mean that Cancun is where they ended up.
Revealing mistake: During the final shootout at Beverly Ambassador, when Luca shoots the cop next to Chris Penn, his blood pack is exposed so badly he literally has to push it to his side out of sight. (01:51:25 - 01:51:49)
Continuity mistake: When Alabama is dragging him out of the hotel her face is miraculously fine when she gets in the car.
