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: During the opening credits the protagonist is talking with his parents. Throughout this, the whiskey in the bottle changes level depending on the shot. (00:01:20)
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.
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.
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)
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)
Visible crew/equipment: Just after Anca has arrived at the party, she hands Ines a shirt. Whilst the two of them talk about the shirt, the shadow of a boom mic can be seen on the door, at the top of the frame. (02:16:35)
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)
Factual error: The movie puts a caption in the prologue "January 2013." Later the protagonist puts the hammer he received by the mysterious delivery right on top of a newspaper, a copy of "Mid-Day" with a retouched opening article (related to the movie murder of course) but headline news with a Sunil Gavaskar quote that dates it as a December 2015 edition. (00:03:20 - 00:10:10)
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)
Other mistake: When Warwick Davis shows Joe the form he's tricked his father into signing to allow him to transfer schools, the form is shown full screen. The "home" phone number is the same as that used in the school's letterhead, and there is text that says"insert name of fictitious school here." Also in this scene the name of the headmaster and phone number is visible, but none of those details match what is on the school's advertising board a couple of scenes later when Joe starts at his new school.
Continuity mistake: At the toll booth, Afonso does a thumb up sign to the operator, not knowing what he really said to his son about their ride. He is doing the gesture with his right hand, left hand, right hand again depending on the shot. (00:07:00)
Character mistake: In the newsreel during the growing tensions, a newspaper headline featured with great importance goes like this; "ABUCTED son not yet found." (00:04:30)
Continuity mistake: John Biswas is tailing the little deaf girl. His scooter breaks down and he follows her on foot. They are walking in the same road in two different shots, with a cut just a few meters apart. The toys in her right hand and the paper in her left swap hands in the second shot. (00:18:20)
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)
Continuity mistake: Carolyn puts on her pink dress and asks Tallulah to zip her up. Tammy Blanchard puts her hair up in a bunch, but there's a large bang to the left side of her face that stays down. In the reverse shot though, she got all her hair up. (00:18:20)
