Continuity mistake: At the beginning of the movie, there is a scene where Rebecca's phone is ringing, and it wakes her up. She grabs the cell off the night stand. She has red nail polish on. When she puts the phone back down on the night stand, her nails are natural, not polished.
Plot hole: The system providing oxygen can only be accessed by someone slim. Therefore John Goodman built the bunker with him unable to access the key facility that provides oxygen in his bunker. Yet he must have been able to go and get Britney when she went to that area?
Suggested correction: It's not a plot hole because he said in the film, the normal hatch to the air filtration was blocked by something that fell on top so they couldn't get through that way.
Other mistake: When Helen Mirren and Will Smith are standing on the subway platform and the scene cuts away to view them from the other side, we see them through the windows of a passing train. Dame Helen suddenly gets out of character and hastily answers her cell phone. She was playing a "spirit" on behalf of Will - not someone who'd have a phone. (01:04:00)
Continuity mistake: The wounds that Juda got on his face from the fall from the horse at the beginning of the film, disappear the very same day.
Factual error: The main character is being wooed by Lockheed - an aircraft company, whose representative then gives him gifts for his kids - one of which is a desk model of an aircraft, however it is of an aircraft produced by one of Lockheed's competitors - Grumman, which would be akin to a GM rep giving a toy Ford Mustang as a gift. Both companies continue to remain competitors as Lockheed-Martin and Northrop-Grumman since the government vetoed a proposed merger back in 1998, and at no time have the two companies collaborated on a major project.
Factual error: Jackie is handling medication vials and taking a pill. Some of the vials have childproof "palm and twist" caps, but they were not invented until 1967. (00:48:00 - 00:49:00)
Revealing mistake: Towards the end of the movie, the principal puts on his hat which turns his hair green. But you can see the green paint has already been applied before he puts his hat on.
Continuity mistake: When Gina and James visit her sister, Gina sits down at the table with the family. Then in a close up with James and Ramon, Gina walks into the same room she should already be sitting in. (00:48:30)
Continuity mistake: Maureen spent the first night in the spooky house, without conclusive results. They are meeting the prospect buyers in a bar. When Lara walks up to them and begins the conversation, the arm position of the man changes wildly between shots several times at every cut. (00:08:40)
Continuity mistake: Maudie lights herself a cigarette. There are 2 matchboxes on the railing of the porch. They disappear for the rest of the scene and Maudie's cardigan and dress do not have pockets. (00:02:35)
Continuity mistake: Henry spills coffee and then goes to the two clumsy detectives' desk checking on their lack of progress with the shredded note. There's another police officer in the background, a heavy man with a white shirt, suspenders and a bald head. This man is, depending on the camera position, sitting at his desk on the phone, or standing talking with another officer. (00:18:00)
Continuity mistake: When they are at Sarah's house, the boy's father tells her to go outside and ask Lucas to pull the van around back. When Sarah walks to talk to Lucas her long braided hair is tucked into her shirt and her arms are crossed. In the next shot when the camera comes back, her hair is on the outside of her shirt despite her arms still being crossed. (00:45:55)
Continuity mistake: The crew arrived at the volcanic island in turmoil, and are talking with the local captain. The captain asks them to carry also some of the dead people, and they start asking him what the plan is, if there's one at all. The pass at the neck of the captain shows the side with the symbol in one shot, the blank one in the next. (00:25:10)
Other mistake: Daniel Blake in the first minutes of the movie is at the hospital taking an echocardiogram. On screen you can see the date of the test; 20/10/2015, so he took it on the 20th of October. The day goes on with Daniel visiting his coworkers, then he is at home, with BBC Radio Four saying it's twelve to 1:00 and broadcasting the first shipping forecast of the day for "Tuesday the 20th." (00:04:40 - 00:06:50)
Factual error: When Steve Carell is telling his nephew Jesse Eisenberg that he is leaving his wife, the view from his 1930s era Hollywood Hills home shows the modern skyscraper-filled LA downtown skyline.
Factual error: The 5th Amendment to the Constitution simply states that "No person... shall be compelled in any criminal case to be a witness against himself." There is no actual or implied provision that means once you have answered a question, you can't plead the 5th on any subsequent questions, as the movie depicts.
Continuity mistake: The chef at the airport stabs someone, but the knife blade is clean afterwards; moments later he stabs it through the valise, and it is covered in blood.
Continuity mistake: The gang Bo is reluctantly part of gets to Maurice's crib where he is playing cards with his homies. The red jacketed one is defiant, and grabs a handful of red and blue chips in front of him tossing them in Angelo's face. But if you check out of the table in the wide shots before this occurs, you'll notice that red chips were never in the stack in front of him to begin with. (00:19:05)
