Other mistake: Jodie mentions wearing shoe size 13 more than once in the movie yet look closely and those are only size 10 shoes.
Factual error: The royal parade is supposed to be of the Yorkshire Hussars, but the filmmakers instead borrowed the King's Troop, Royal Horse Artillery, complete with guns. Although the uniform was similar, the Yorkshire Hussars was a cavalry regiment until the Second World War, when it became an armoured regiment. It was never an artillery regiment.
Continuity mistake: After Wesley has intimidated the snot bully, he comes back home and finds the police. Sitting at the table, his mom holds his arm and says "Wesley, Mr. Chambers asked you a question." Mary Elizabeth Winstead has her right arm on the table, close to her body. Change of angle and she is holding the coffee mug instead. (00:45:10)
Continuity mistake: At the beginning of Aiai Liu's flashback, she is on a boat. Fellow prostitute Ping leans forward towards Hua saying he should treat them all fairly. Aiai she is intently cleaning a fingernail in one shot, immediately after she has the same hand placed on her cheek. (00:32:45)
Other mistake: From the time Eliza exits the bar until she drives away, there are discrepancies in the scenery: there are or aren't parking spaces along the road; there's a lot of space between her truck and the truck in the next parking space, but not when she's backing out; the man rattling bottles by the garbage cans is further from the building and her truck when she's getting in and should be visible when she's backing out but isn't; her truck's rear end would be partially blocking the traffic lane, etc. (00:03:15)
Continuity mistake: When Hodaka first fires his gun whilst being threatened by the man, the shell casing lands on the ground beside him, right next to his head. A couple seconds later, when Hina goes to help him up so they can run off together, the shell casing has vanished from the ground. (00:22:06)
Continuity mistake: When Mr. Laurence, Laurie and John Brooke are having Christmas breakfast, John puts his hand on the table but in the next shot, his hands are not there. (00:29:37)
Revealing mistake: There's definitely more than one cat playing "Panda", but how many can't be determined because Panda's entire body is not shown at once. "All" of them (maybe a whole litter?) have various distinctive black spots on a mostly white body. Watch for the amount of black on a cat's face and whether or not the diagonal black fur on the right side covers the entire eye or only half and if there's a black spot toward the nose. Also, look for how much black is on its side, back, behind its legs, etc.
Factual error: Mohegan Sun casino is in the state of Connecticut. Connecticut does not have legalized sports betting and did not have it in 2012, when the film is set, therefore Julia would not have been able to place Howard's bet.
Other mistake: Elsa Brecht is holding an official piece of mail sent from the Coconut Grove Hotel in Miami but it's postmarked Orlando, Florida. There's no legitimate reason the mail would be postmarked Orlando when Orlando is 235 miles from Miami. (01:24:16)
Continuity mistake: Ellen and Joe just got out of the motel room and begin walking towards the marina. Left of frame, a young couple (she has a cap and denim, he has a full carrot top and a bright red plaid shirt, can't miss them) walking up some stairs on the left, going in the same direction as they do, different path. At the next cut, they are walking down the same boardwalk as Ellen and Joe and in the opposite direction. (00:04:30)
Continuity mistake: When George gets shot, he lies flat on his back. When Gloria walks in on the scene, there's a closer view of him and he is lying on his side. (01:18:45)
Other mistake: Judy is singing on stage with some showgirls. She is singing into a wired microphone. At the end of the song she twirls around twice, but the microphone does not appear to get wrapped around her. (00:49:35)
Continuity mistake: The protagonist is at the lunch table with his auntie, and is trying to get her to fund his 'enterpreneurial' efforts. After the prayer, she asks him "You want some hot sauce?" Eddie Murphy goes from having his hands joined to having them on his hips. (00:20:25)
Continuity mistake: During the sign-up for the app at the beginning the girl says "I want to be Sarah." Look at her hair; mostly in front of her left shoulder, just a couple locks on the right side of her face. At the cut, hair behind the left shoulder and a bigger right bang. Camera angles and hairstyles switch again back and forth. (00:02:30)
Factual error: In 1915 Tolkien was commissioned as a Second Lieutenant with the Lancashire Fusiliers. He (plus various other officers) is constantly shown in the film wearing bright metal cap badge, collar badges and shoulder titles on his Service Dress tunic and greatcoat. However, in the Lancashire Fusiliers officers did not wear shoulder titles on their SD tunics/greatcoats, and their cap/collar badges would have been in a darkened bronze finish, not bright metal (which was for Other Ranks and NCO's).
Continuity mistake: During Stella and Will's walk, Will's scarf was consistently wrapped one time around his neck, but the length of his scarf on either side varied. The right side was usually much longer than the left side, but the ends were about even other times. When Will was lying in the snow, the scarf ends were almost equal (reaching about half-way down his coat); when he stood up, the ends were far apart. After he fell in the snow, Will got up and adjusted the scarf ends to be about the same in length. (01:25:35 - 01:29:30)
Revealing mistake: It was pouring when Adam, Hannah, and Megan got out of their SUV to talk to the Man and try to get help with the flat tire. As they stood there, no "rain" was hitting them and it became obvious that their partially wet-looking clothes were "pre-wet" - they returned to the SUV with the same amount of "wetness." Also, the rain was coming down in straight streams, all parallel. (The water flow appeared to be slightly angled to make the artificial "rain" look more natural).
