Continuity mistake: After Gerry gets smacked in the face by the 'broken' suspender clasp, we see the silver clasp land under the dresser. Yet, when he's moaning and lifting his leg to get onto the bed, we can actually see the clasp still intact on the front suspender that came loose, which is dangling right behind him (just look between his legs). Of course, in the next shot, that clasp is gone. Since the silver clasp is one of the plot points, this is bizarre to say the least. (00:11:10)
Factual error: When Chigurh is in the gas station and throws the wrapper on the counter, the "Nutrition Facts" are visible on the label. Set in 1980, the "Nutrition Facts" label wouldn't have been available for at least another fourteen years, as nutrition labels were started in 1994.
Continuity mistake: There are two scenes during which Harry is shown having visions of the Dept of Mysteries while he is asleep. The first scene occurs after Harry's confrontation with Seamus in the Gryffindor common room. There are shots of Harry lying in bed wearing a short sleeve, crew neck tee shirt, but when he is startled awake by the vision of Voldemort, he sits up wearing a buttoned henley tee. The next day is the first day of Defence Against the Dark Arts class with Umbridge. That last shot of Harry in the henley tee shirt was cut from a later scene. Later in the film, when Harry has the vision of Arthur Weasley's attack, he is wearing the henley tee shirt. (00:34:00 - 01:09:35)
Factual error: During the fight scene with Sandman in the armored car, the Terminal Tower can be seen in the background, which is a landmark in Cleveland, Ohio (where the scene was shot), not in New York City.
Continuity mistake: When "Emperor" Moe appears in front of Marge, after she and the kids return, the two cartridge belts swung over Moe's shoulders switch from his left over the right, to his right over the left. (01:04:50)
Revealing mistake: After Steven Wilkins disguised as a vampire kills the unnamed woman he closes her eyelids to make it look like she's asleep. Just before his hand contacts her eyelids you see her almost blink, revealing she's very much alive.
Factual error: Federal institutions have strict rules for inmates or patients based on the reason for their incarceration, including substituting metal utensils with safer plastic ones. Despite being convicted of brutally killing his family, Myers is still trusted with a sharp metal fork - resulting in the nurse's death.
Factual error: When Swagger is fleeing from the police in the car wash after being shot, the radio says that he is at a car wash at 9th and Girard. There is no such intersection. On Girard Ave, 9th street picks up south and north of that street.
Continuity mistake: When Nick is sitting on the bed talking to Jessica, her position changes from lying on her side to lying on her back, as the camera angle changes.
Visible crew/equipment: At Hoover Dam, after the salute, when Defense Secretary Keller speaks with Lennox and Epps, the reflection of the white reflector screen is visible on Keller's glasses. What's more, the boom mic's reflection is actually visible within the reflector screen's reflection. Two for the price of one. (01:35:30)
Continuity mistake: After receiving the phone call from Nancy, when Robert and Morgan are talking in the taxi, his seatbelt repeatedly changes from over to under his trench coat collar. (00:16:45)
Continuity mistake: On the small sand spit, when Jack, Elizabeth and Barbossa meet with Will, Beckett, and Davy Jones, the leather cuff Jack wears on his right hand actually disappears and reappears twice during the meeting.
Plot hole: When Bridgette ran through the glass and Linda and Jim were at the hospital Jim tells Linda he called her mom and told her what happened and she was coming to stay over the next day. Yet apparently her mom forgot what happened because she had her committed because Linda didn't remember what happened to Bridgette's face. Also, Bridgette was like 9. How come no-one just asked her what happened?
Continuity mistake: During the fight between Aslo and Silas, Aslo is seen lying on his back in a closeup. But when the shot changes to a wide shot, he is suddenly on all fours.
Revealing mistake: In the day following the Rider's first ride, Cage shows up at the street that has been burned down the center. A person very close to the beginning of that scene walks on the broken up rocks and it moves as if it were a pad or a sponge. It wasn't a rock moving because the street moves with the rock. It happens a couple of times during that scene.
Factual error: Ben, Abigail and Riley arrive at the Library of Congress to take the President's Book very late at night. However the Library of Congress, despite being shown as open, consistently closes at 5 PM.
Other mistake: The closing captions state that Chris McCandless' sister Carine flew "his" brother's ashes home, instead of "her" brother's ashes.
Factual error: It's late 18th, possibly early 19th century and, as Jane and her sister walk along the beach, a construction crane is visible on the horizon.
Continuity mistake: At the start, Robert Neville drives into some yellow poles, only to drive into them again in the following shot.
Continuity mistake: Before the school bell rings, Jason asks Ms. Darbus for her favorite summer memory. When everyone turns to look at him in the shot from the front of the class, there is a book under Troy's desk, which is not there in the previous or following shots. (00:01:25)
