Continuity mistake: When Daisy walks away from Max on the roof in Vegas, the food and the napkin disappear. In the next shot, they reappear.
Other mistake: When Kate is taking the Medical-Surgical Nursing Exam, there are 2 separate #23 questions at the bottom of the page. (01:09:30)
Continuity mistake: Anna and Rebecca are sitting on a bench in the golf field holding glasses of wine when Jerry and three of the others ride by in a high speed golf cart chase. Anna stands up to shout at them and slings her glass, spilling most of her wine out. She then turns back around and the camera cuts, and now her glass is back to half full. (00:51:40)
Continuity mistake: During the fight at Aunt May's house, May knocks Tombstone out of the house with a bat. The subsequent shots have him back in the house.
Continuity mistake: At the beginning of the movie, the teacher asks "Has Nicky's mom volunteered?" The guy answers "Emily?" with his arms down his hips, but he had his arms folded across the chest just in the previous shot. (00:03:50)
Continuity mistake: When she is painting the wall and stops to go and hug him, in different shots during the hug the amount of white she has painted lessens, and has a different pattern. (00:07:45)
Continuity mistake: After Elizabeth drives her motorbike off the peer, across the frozen lake and stops while she looks back at the police, the Ducati suddenly has different tires than earlier in the escape sequence. (00:25:55 - 00:27:05)
Plot hole: As the evolved Predator's ship takes off it leaves Casey Bracket alone in hilly forest terrain. The ship then flies a long distance before crashing and the Predator and McKenna start fighting, just for Bracket to show up and help out of nowhere. Impossible for her to cover that distance that fast in hilly forest terrain.
Other mistake: Towards the end, Chewbacca and Beckett have walked some distance from the landed yacht. They come up a small slope and are faced with Han, waiting for them. But an aerial shot shows that slope is very short and just runs down to a cliff. There's no way they could have got to the base of the slope to walk up it in the first place.
Factual error: Dobermans were not introduced until the 1890s, let alone their ear cropping. (01:00:15)
Revealing mistake: Baca is using a pistol to shoot the zombies towards the end and still has this same pistol at the end. When he's on the ground about to shoot himself to stop from turning, it shows a close up of his pistol which reveals it's a 6mm BB gun. (01:20:15)
Continuity mistake: When Newt is straddling Thomas with a knife pointed down at his upper left chest, it's very obvious that the knife goes into his chest, through Thomas' shirt. A few minutes later, when Thomas is kneeling over Newt, after Newt stabs himself in the chest, the stab hole in Thomas' shirt is no longer there and he isn't bleeding. (01:50:45)
Other mistake: When the detective sends the traffic cam footage, a Gmail alert pops up. However, the dad is currently using Margot's computer, not his. He previously logged into Margot's gmail account on this computer so any alerts received would be Margot's mail, not his.
Continuity mistake: When Buster is shot, his hat with the hole in it disappears.
Factual error: Jonah Hill references "Chucky" from the movie Childs Play. This movie's period is set somewhere in the late 1970's. The movie Childs Play didn't come out until 1988.
Plot hole: There is no way Anna could know that Hester was going to be at the auction. The circumstances that led to Hester and Tom being captured can't possibly have spread to the Anti-Traction League, they were immediately taken to the slave auction after being captured. Anna also instantly recognizes Hester when she sees her despite the fact that Hester was 8 years old the last time she would have seen her.
Suggested correction: Anna might have very well just been there to do anti-tractionist things, it was an auction made of towns after all a prime target to hit many options at once or hide bombs on for a bigger city to gobble up and go off later. Once she saw Hester her plans simply changed. As for how she recognized her, it is possible Anna had been tracking / keeping an eye on her. It wouldn't be impossible to ask around for a scar faced girl moving from town to town and might have gotten a pic somewhere.
These are all wild guesses that aren't confirmed by the film itself. They do not qualify as corrections.
Continuity mistake: When RBG leaves for court (about 30 minutes from the end the movie) her brooch is on the right lapel of her black suit and when she gets out of the cab, it is on her left.
Continuity mistake: Juliet is on the bed with little girl Kit. The child has a ribbon is her hair then looks up at Juliet and it becomes a slide. Next cut it is a ribbon, then a slide. Then the girl sleeps on Juliet with just a ribbon visible. (01:19:00 - 01:20:00)
Continuity mistake: The dog poop on the ground moves when the father first pulls his car into the garage.
Other mistake: The red rescue helicopter which is approaching and crashing is a Jet Ranger while the model filmed later on the crash site is a MBB BO 105. Most obvious are the differences in the landing skids and the front nose of the cabin. I guess the Prop used for the ground filming was an actual abandoned helicopter. The approaching and crashing helicopter is most likely CGI, so it should have been easy to have them matched. (00:15:00 - 00:21:00)
