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.
Continuity mistake: While Sam puts Slappy on the junk cart the sun changes between shots.
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: 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.
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)
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)
Factual error: On two occasions a ring neck dove lands on the sailboat. The sailboat is making way to Hawaii. Ring neck doves are indigenous to Africa, not Hawaii. They are also not an introduced or invasive species in Hawaii.
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.
Audio problem: When Mrs. Hudson finds a package for Sherlock instructing him to open it before the trial, she says "I never even heard anyone knocking" whilst handing it to Watson, but the line appears to have been dubbed over as her lips don't match up with the dialogue.
Continuity mistake: After Dumbledore gives Newt the card for the safe house in Paris, they teleport to a bridge where they continue talking. Dumbledore then tells Newt why he likes him so much, and in the side shots, Newt is shown holding the card up. When it cuts to angles from behind Dumbledore's shoulders, his arm and hand are much lower with the card and his head turned in a different position. (00:20:35)
Factual error: The movie is set in Van Diemen's Land (now Tasmania) in 1825. Throughout the movie, in scenes where Clare talks to the aboriginal tracker, Billy, subtitles state that they are speaking in Palawa Kani. Palawa kani was developed in the 1990s by the language program of the Tasmanian Aboriginal Centre, more than 165 years after the movie.
Continuity mistake: In the opening scene with the skype call, Mia's hair is in front/behind her shoulders depending on the camera angle, with no logic. (00:00:55)
Factual error: There are no law enforcement agencies referred to as "Mounties" in Alaska, or any elk.
Continuity mistake: The mayor suffers a bleeding head wound while evacuating City Hall. Several scenes later he is shown with no wound at all. Not even his hair is mussed. (00:40:30 - 00:46:30)
Continuity mistake: When Jason lunges at Batman with his knife, there is a pile of garbage by the wall where he lands. In the first shot the barrel by the garbage is wooden. But in the next shot it's suddenly a metal barrel/drum. It then changes back to a wooden barrel again. (00:04:20)
Continuity mistake: Felix on his skate jumps over a rolled-up rug some movers are carrying in the middle of the street. He jumps and the street is in the shade, he skates away and the street is full of sunshine. (00:01:30)
Continuity mistake: Princess Dawn is in her chambers and her servants are preparing her for the coronation. When her book-headed valet tells her "You have come of age", he is suddenly holding the tome with both hands, while he had just one on it before the cut. (00:19:30)
Continuity mistake: When Captain opens the bridge gate he puts his right hand to his chest. From the opposite shot it's down.
