Factual error: In the evening check at the dormitory, when the girls are found missing, the nun calls Daisy Kalibil. In real life the 8-year-old Daisy was promised to a man named Kalibil whom she married later, but at that time she was still Daisy Craig. (00:31:20)
Continuity mistake: In the scene where White She Devil is pursuing Undercover Brother on a motorbike, her helmet changes from one without a visor when the shot is a close-up her face, to a different helmet with a visor when the shot is from further away.
Continuity mistake: In the scene where Stallone is chasing and shooting at the killer in the factory, he bursts through a door and shoots the hanging body of the FBI/SWAT officer. In the first shot of the officer you can see his lips. The next shot of the body shows that his mouth is duct taped.
Continuity mistake: In the scene where Joe Nast goes to the post office to get back the wedding invitations, Bertie invites him to come through the little window into the back to help her find them. As he crawls through he accidentally kicks the bell off the counter. However when the shot changes to the interior of the mail room, the bell is still on the counter. The DVD commentary states that this shot was done on a stage in a studio, and the former shot was an actual store. Jake Gyllenhaal admits to having purposefully tried to knock the bell off, so it seems that when the studio shot was being made this detail was forgotten, or it was shot beforehand.
Continuity mistake: In the scene where Justin arrives home from school, Richard is on his bed wearing a black hooded top and long coat. The camera angle cuts to beside the bed, and Richard is only wearing the black hoodie (it goes just to his waist), then as he stands up he is wearing the long coat again.
Continuity mistake: Hadley is in the hospital and she is talking to Alicia. Later on in the scene Alicia goes home. Hadley's dad walks in and she makes him call Alicia to take back his promise. When he phones her it has only been like 2 minutes and Alicia is home from the hospital. How can this be.
Continuity mistake: In the scene where Christina decides not to be afraid anymore and runs after Peter, she comes out of the house and first shouts while facing in the wrong direction. She knew that he went the other way, because she saw him leave. (Shot at different times, confirmed on DVD commentary.) (01:19:25)
Continuity mistake: In the scene where Winnie and Jessie are going swimming, when Winnie takes off her dress, you see that her right foot was not completely out of the dress. Then in the next shot, you see Winnie jump in without moving her dress at all, and it is far away from her on the rock.
Continuity mistake: During the final pool sequences, there's a quick glimpse of the main character's left (broken) wrist. It's normally all purple and gross looking, but in a brief shot, you can see his left hand shooting the pool cue and there is no purple swelling.
Factual error: Frida is shown watching King Kong when she goes to New York. It is well known that the movie was made in 1933, but later we see on her mother's grave that the year is 1932.
Continuity mistake: When Lanie is talking to her sister at her sister's house, they are seated across from each other on sofas. Her sister has a plate of cookies in front of her on the coffee table. As Lanie and her sister are talking and her sister gets up towards the end of the scene, the plate of cookies have moved across the table in front of Lanie.
Other mistake: Fleeing with Little Creek from the fort, Spirit destroys small railing to free horses tied to it. But after the pole gets torn off, it leaves an empty space on the ground, without any hole or at least broken remains.
Continuity mistake: When Davey Stone is running away from the police while singing, after he says, "But I'll give this old lady's melon's a squeeze.", he swings around a street pole. The garbage can lid he is riding on has no handle, but when he slides down the hill and jumps over the front of a snow plow, the lid has a handle.
Continuity mistake: About 35-40 minutes into the film, Jules and Jess are at the bus stop. Pinky's future in-laws drive by in the Jaguar with nothing in front of them. When the camera shot moves back as they enter the bend, another car has appeared in front of them.
Factual error: Near the end of the film when Barnes exchanges fire with Rudy and U.S. Customs Agents, he fires eleven shots from a revolver without reloading. (01:24:05)
Continuity mistake: When Belinda says "nice sweater" to Jamie, Jamie has a backpack on. When Jamie walks away, her backpack disappears. (00:11:55)
Continuity mistake: Bret shoots himself under the chin and a hole is blown in his forehead. Moments later when he's on the ground, for a split second, you can see his forehead completely unblemished. (01:03:00)
Audio problem: In the beginning when Davey is burping, the sound of the peoples' glasses breaking is a little early.
Factual error: When the engine is shut down in the plane, the altimeter is shown spinning down wildly, indicating that the plane is diving at a speed of over 2000 feet per second, which is approximately 1200 miles per hour. Assuming that the plane wouldn't disintegrate at that speed (which it would), judging from the altitude at which the engine was cut, it would have taken less than 3 seconds for the plane to hit the ground.
Factual error: When Uma Thurman has just picked her mother up from work, after her mother's boyfriend doesn't show up, they are stopped at a red light. As they are sitting there, a tan late 90s (or later) Chevy Sedan comes across the intersection in front of them. This movie is set in the early to mid 80s.
Suggested correction: According to IMDB.com, the movie is set in 1987, not the early-mid 80's.
