Character mistake: When Stuart calls home from the pay phone he's talking into the wrong end of the phone.
Character mistake: Barbara is in her office looking for the one item they need help to identify when Diana walks in. She says "OK, item number 23." She suddenly finds it saying "here it is" and reaches in the box to grab the Dreamstone. The ticket says item #24. (00:22:18 - 00:22:50)
Character mistake: At the beginning of the scene where the vampire hunters leave London in pursuit of Dracula, Jonathan narrates, "By train we can reach the Romanian port in Varna in three days." However, Varna is a Bulgarian seaport. This can even be seen on the map showing the Turkish invasion of Eastern Europe in the movie's prologue, and on the map that Jonathan studies aboard the train at the beginning of the film. (01:45:35)
Character mistake: Selena Gomez drives into town in a fully restored 1967 Pontiac Le Mans, which is a long box shaped car. However, when confronted with Bill Murray and Adam Driver, Adam Driver complements her on her 1968 Pontiac Le Mans, which is a completely redesigned shorter curved body style. The two look nothing alike.
Character mistake: In the final scene, one of the newspaper clippings on the killer's office wall reads something like, "Huge Mudslide in Mexico: All Killed Expect Newborn." The penultimate word should be "except." (01:35:55)
Character mistake: During the opening space battle, Obi-Wan's ship falls under attack by buzz-droids, who proceed to cut into his fighter, disabling a number of systems and leading Anakin to try some decidedly dangerous moves to get rid of them. Both Anakin and Obi-Wan are acknowledged experts in the use of the Force and both have been shown to use the Force routinely, even for relatively mundane activities. It's also been firmly established that the Force works on droids and that the Force-user can still affect others through windows, viewscreens and so forth. Yet neither thinks to use the Force to deal with the buzz-droids. (00:05:10)
Character mistake: At the memorial service the principal says that it's been 39 days since 39 loved ones had died. But there were 40 students on the plane and 4 chaperones, making the total 44. Now 7 people got off the plane, which means 37 people related to that memorial service actually died, not 39. Two pilots would make up the numbers, but there would be flight crew too, which still leaves the numbers off.
Character mistake: As they take Han away, watch Lando. Just before he tilts his mask down so we can see who he is, he whacks his head on the doorway. (00:16:20)
Character mistake: When Wood is telling Harry the rules of Quidditch he says that if you catch the Snitch the game is over, which is true. But then he also says that which ever seeker catches the snitch, their team wins, but that isn't true. Granted that the 150 extra points probably would give you the winning lead, but as JKR pointed out in the 4th book at the Quidditch World Cup, you can catch the Snitch but lose the match. And you'd think explaining the rules to a first-timer you would want to get it right. (01:05:40)
Character mistake: During the opening scene, the girls are playing volleyball. The score was announced, and game point was announced. When the ball is served it comes to Sue, she hits the ball twice, in succession, which is against the rules, she is on the same team as Carrie. This should have ended the game, but the point continues, the team they are both on gets the ball over the net, then it comes back, right at Carrie, she does not hit the ball, then the game is over, and a few of her teammates can be heard saying various insults about her inability to play the game and so forth. If they would have been playing by the rules, the ball should have never even came to Carrie.
Character mistake: One of the top most taboo things for a super hero to do is reveal any aspect of another hero's identity to someone, especially a villain. But when Flash is trapped by the gray adhesive and the other Justice League members are about to take the villains away to disarm the bombs, Flash tells Green Lantern "Hal, go", calling Green Lantern by his first name right in front of Mirror Master. (00:08:05)
Character mistake: Chapman is wearing a gold oak leaf cluster insignia on his uniform which is the rank of Major. At the initial briefing he is introduced as Major, which is correct. Throughout the movie he is referred to as Captain, which is wrong.
Character mistake: Dwanye Johnson is called onto the ice, the first thing he does is throws a player through a glass pane. The player looses a tooth. The close up shows that the tooth is a molar, but the commentators say, seconds later, "Ohhh that's an incisor!" (00:01:00 - 00:02:35)
Character mistake: When Edward leaves Forks, he does it because he believes that he will be protecting Bella. Except that he seemed to have forgotten that Victoria was still in Forks and was intent on killing Bella.
Character mistake: Chick Gandil mispronounces Eddie Cicotte's name, calling him "Si-coty" instead of "See-cot."
