Other mistake: Near the start of the movie Jon indicates that he has titanium in his right arm, but towards the end of the movie the bullet ricochets off his left arm. (00:08:55 - 01:34:45)
Other mistake: When Dom and Cipher break into Mr Nobody's base, they use "the latest in concussion grenade technology which scrambles all senses and lasts an hour" which would include vision and is reflected as such. 2 min later Letty and Hobbs are able to see the kiss Cipher gives Dom.
Other mistake: At the end of the movie, when Cory is in Natalie's bedroom, Cory stops and looks at a picture of Natalie and his daughter wearing a high school graduation cap and gown. Cory said his daughter was only 16 when she died so she would've already been dead by the time Natalie graduated. (01:36:00)
Other mistake: When Hercule Poirot is interviewing Mary outside the train, the teapot in the middle of the table has a spout (pointing directly to the right, towards Mary) but no handle on top or the opposite side, towards Poirot, where the handle should have been.
Other mistake: The phone wire was cut in the boy's room when he called his uncle. Yet his uncle used the same phone to make a call just before he died.
Other mistake: Bo (obviously an adult), who worked with Kevin, was able to walk into the high school cafeteria and take Phoebe into a hallway to talk without any school personnel seeing him or questioning his presence. (00:30:10)
Other mistake: With the major exception of the check-out counter, the used book store has few discernible shelves. Books are literally stacked on top of one another (perhaps 50+ high) with no space between the piles. The books are not even aligned. It would be almost impossible to find a book or try to remove one without all the books falling. These can't be real stacks of books. (00:30:24)
Other mistake: The private investigator has a full size Glock. The Glock 21 which is a .45 ACP has the lowest magazine capacity of 13 rounds. The 9mm capacity for the Glock 17 is 17 rounds. The PI exchanges gun fire and after he fires 7 rounds, his gun runs dry. Makes no sense to bring a half empty gun to a fight, plus he just got it back from his brother-in-law. (01:05:00 - 01:06:00)
Other mistake: Eddie, Johnny and Vance are under fire on the roof of the mall from a sniper who wields a single-action rifle that he reloads, manually, slowly, distinctly pulling the level in the close-ups, but that somehow when he is not in frame fires shots in rapid succession. (00:38:45)
Other mistake: Anne makes the Oscar Wilde joke right before Bill kills himself, but he mentions it in the suicide note, which he obviously wrote long before.
Suggested correction: He wrote 2 letters, a longer one in the dresser drawer that he had spent time writing, and one that he wrote immediately before going to kill himself, explaining what he had done. The shorter one (referencing the Oscar Wilde joke) was written that evening while his wife was asleep on the couch.
Suggested correction: What evidence is there that he didn't write the suicide not that day?
It doesn't matter if he did, the point is he definitely wrote it before the Oscar Wilde joke. Right after the joke, he goes to the barn and kills himself. Anne is still on the couch, she hears the gunshot, she gets up and finds the note.
Anne is on the couch, then it cuts to him in the barn. He could have easily written his note between the two shots.
Other mistake: This film shows that John Kramer is buried in a public cemetery, complete with an identifying headstone. Given that he was a notorious serial killer, his remains would not have been buried in a public place, as it would cause his gravesite to become a macabre tourist attraction.
Other mistake: When Harry Hole gets a call but isn't there to answer, Katrine Bratt picks up the phone and takes a message. Rebecca from Telenor Security tell her they picked up a cellphone signal from a missing person. She tells her the coordinates as Parkway 1, 0139 Oslo. On Katrine Bratt's computer you see the coordinates as Parkway 1, 0350 Oslo. (01:13:15)
