Visible crew/equipment: When Yu and his friends have finished dragging Yoko into the van, Yu jumps into the van and closes the door behind him. When he finishes closing the door, the reflection of the boom mic can be seen in the window. (02:44:50)
Continuity mistake: The neighbors are dripping wet as they get out of the hot tub, yet they don't drip any water when they get onto the trampoline.
Continuity mistake: When the mother puts the drawing from her daughter in her pocket she puts it in the left pocket of her jeans. When she takes it out later, she takes it from her right jean pocket.
Deliberate mistake: In the final fight, two master Brazil Jujitsu fighters, one an instructor and the other a champion, execute rear naked chokes without the requisite body locks, using the legs to control the body. In the first case, Mike was able to escape the choke by flipping backwards, which a body lock prevents. In the second case, Mike was able to strangle Silva even though any trained fighter could prevent it by simply twisting their body. (01:30:00)
Continuity mistake: In the scene at the end of the film at his grandfather's empty lake house, Simon first unloaded the wooden Christmas figures from his duffel bag onto a pile of firewood on the dock. He then went into his grandfather's workshop and sawed the scroll off of his mother's violin. With his phone, he took a picture of the severed scroll in his hand with the dock in the background, but the dock was empty.
Revealing mistake: At the beginning of the funeral for the girl who died in the motorcycle accident, the supposed corpse can be seen breathing. (01:14:35)
Continuity mistake: When Michelle and Leonard are up on the rooftop for the last time, the left side of her hair keeps swapping from being behind to in front all the time.
Continuity mistake: There is a modern coffee thermos container on the sink by the window during a scene set in the 1930s. In the next shot, it suddenly disappears. (00:46:25)
Factual error: When Natalie decides to rebuild the carburetor that Keith gave to her, she opens the rebuild kit and starts lying out the parts. The problem is that the kit is for a French Solex type 30 single-barrel carb, and the carburetor in the box is a domestic four-barrel.
Continuity mistake: When we first see Agent Holloway viewing the crime scene photos taped to the wall, he is facing camera looking at transparent pictures on a transparent wall (as if we are behind that wall, seeing through it). When the angle changes to see the Agent from behind, the photos are now paper photos on a normal, opaque wall and the pictures are arranged somewhat differently - most notably to Holloway's right near the top where two wider photos are vertically aligned atop and below each other in the second shot when they were misaligned in the first shot by nearly half their width. The transparency versus opaque materials issue is a stylistic choice of the director and not a mistake, but the mismatched alignments is a mistake. (00:11:25)
Revealing mistake: When Ricky and Brandon are on the ferry, the camera shows Ricky reaching down to grab Brandon's butt and then it cuts to Chance and Eddie. If you look closely, Ricky and Brandon are re-creating the scene they just performed.
Continuity mistake: When King is fighting with Lazarus in the bar, Lazarus gets blood near his mouth like you get when getting hit in the face. But when they fight near the white door, the blood is gone. (01:13:00 - 01:18:00)
Continuity mistake: Mike Manador watches his girlfriend Gina drive away in a taxi. Behind him a truck can be seen coming down the street. Mike then steps out into street seconds later, but the truck has vanished. Next shot looks up the street and sure there is the taxi but no other vehicles, and you can see the entire street. (01:41:25)
Factual error: Geological surveys of the Normandy beaches were carried out months before the invasion, using divers sent ashore from midget submarines, not geologists a few days before.
Character mistake: Throughout the movie, all of the drill sergeants and First Sergeant Morley are wearing their drill sergeant badges too low. The badge is supposed to be centered on the right jacket pocket.
Visible crew/equipment: In the scene of the rehearsal dinner, when they start toasting, several cameras are visible. Not the guy's handicam, but actual cameras.
Continuity mistake: Gina's father opens the door, club in his hand, and finds his family inside for the surprise party. In the reverse shot, Gina's position is also mirrored, having the right arm raised instead of her left. (00:08:15)
Audio problem: When Pavlov is speaking with the doctor, we hear him finishing a sentence with "say, a doctor, perhaps" but his motionless mouth and jaw show he isn't speaking at all in the side shot. (00:19:00)
Continuity mistake: When Abby is finished washing the dishes, she tosses the towel she was using and it lands on top of a red can. An immediate close-up of the towel on top of the can proves this (0:25:29). A second later, the picture zooms out again to show her bending over from exhaustion (0:25:30). The towel is no longer on the can, but behind it against the wall. Abby follows the shop owner into a room adjacent to the kitchen and when they come back, the towel is once again on top of the can (0:25:55), but most of it is inside the can this time. It's obvious that neither her nor the shop owner has touched the towel and no one else is in the shop. (00:25:25)
Revealing mistake: In the opening scene, when Van Damme kicks an opponent onto the boot of a London Taxi Cab, you can see the dent from previous takes.
