Continuity mistake: At the end when Sarchie is hugging his wife, in one shot the bandage on his arm has unravelled. In the next, it is neatly wrapped.
Continuity mistake: The glass window the guy jumps through shrinks in size and has more glass in it in the next shot, when the copper looks through it. (01:03:00)
Continuity mistake: Everly says she has a gift for her girl. Her mother is holding Maisey's shoulder with the bare hand, but in the next shot her hand is inside her sweater, and bare again in the following. (00:40:20)
Continuity mistake: During the "Perfect Puppy" silly song, Bob places a newspaper he had been reading on the couch beside him when Larry starts singing. When Bob shows Larry the picture of the dalmatian, the newspaper has vanished. When the shot cuts back to Bob, the newspaper has returned. (00:16:55)
Continuity mistake: Judge Pendergast calls the daughter of his therapist, who reacts with typical New York aplomb. During the scene, the same extras continue to walk back and forth with no logic, sometimes coming twice from the same direction, even. Most egregious example the blonde with a ponytail and sunglasses on top of her head. She is behind Jennifer Aniston in the opening shot and appears at least 4 times (possibly more but there's another blonde too -unless it's the same one who occasionally removed the glasses) and walks away from Aniston and Forte two times in a row. (00:17:40)
Continuity mistake: When Dex sees "his" son for the first time, the kid in close-ups is playing with the toy that dangles from above, and there's a toy football by him. In the wider angles none of the above is happening. (00:38:40)
Continuity mistake: In long shot where Lou is holding a railroad tie over his head it is turned long edge pointed up, then when the shot returns to a close up it is flat.
Continuity mistake: The glass that was dropped and shattered on the floor had a different pattern of fragments when Mitch [Robin Williams] knelt to clean it up. Most obvious was that the majority of shattered pieces settled toward Mitch's feet but were on the opposite side of the largest piece of glass during clean-up. There's also a "stupidity" in the way Mitch wiped up the glass - pressing down on the thin towel (apparently to entrap fragments), which is most likely to result in getting pierced. (00:01:40)
Continuity mistake: The dog the boys were trying to catch was facing the fence with his nose very close to it. After one of the boys threw a blanket (or piece of material) over the dog, the dog was facing them instead of the fence. Also, the dog was not as close to the fence and the background didn't appear to be the same. (00:06:07)
Continuity mistake: At the end of the movie after sergeant has been shot, they are rushing him to the hospital. Watch the headrest of the passenger seat. It is in place, and then when he is getting in the car, the headrest is gone. Then, it is back in place again.
Continuity mistake: In a scene at a night club, Colin Firth's friend has a glass of red wine in his hand and then he has a glass of white wine.
Continuity mistake: Kevin Shepherd pulls over in front of her fiancee's dad. It's still a wide angle, but you can see distinctly both her and his left arm stretched forward; she is looking at her engagement ring, he has his hand on the steering wheel. Before the camera cuts away though, he lowers his arm; it is not acknowledged in the new shot, where both have still their left arm forward. (00:03:35)
Continuity mistake: When the young girl is on the beach removing her socks, she takes three socks off.
Suggested correction: Jess is wearing yellow socks with polka dots, and yellow wellies. There are three shots in which we see Jess removing or tossing her two yellow polka dot socks, and one of her yellow wellies.
Continuity mistake: The car the hybrid man pushes is in OK shape at first, then he lifts and flips it through the copper fence, and now its whole front side is gone. They might used an already wrecked "car double" for the scene when it crashes and explodes. (01:40:50)
Continuity mistake: During the sniper shooting of Adrien Brody, you have both brothers standing outside of the bank door in the pouring rain. The rain is visible during this scene, but after the sniper shoots the suspect in the head and the Brody falls to the ground, during the closeup when the police move in, there's no rain drops on Brody. Hayden Christensen is still standing up with rain falling around him.
Continuity mistake: When Paul steals the Camaro, he pulls wires out from under the dash to hot wire it. But after he gets his daughter he suddenly has keys.
Continuity mistake: After David hits Hugh he gets a wound on his mouth which gets smaller the next day.
Continuity mistake: When April shoots the alien, they all go outside to look at it. Behind them, you can see the windows boarded up, but they don't board them up until later in the movie.
Continuity mistake: When the plane is on the ground, it has two engines. When it takes off, it has four.
Continuity mistake: When Elizabeth Banks is getting out of Amos' car, when they get back from Bible study, from Banks' angle, you can see that his hand is on the knob on the steering wheel, whereas when the camera changes to Amos' angle, he isn't touching the knob. When the camera changes back to Banks, you can see his hand back on the knob. (00:48:10)
