Continuity mistake: Stan is sitting at his desk listening to the answering machine messages and failing to do anything productive. During the whole scene, the handle of his mug switches orientation, pointing at him in every faraway shot, pointing to his left in every closer shot. (00:04:25 - 00:05:30)
Continuity mistake: At the end of the movie, the bloody handprint on the car changes entirely the second time it is shown. (02:02:45)
Continuity mistake: The protagonist's music video dream gets interrupted by Victor strumming his guitar and asking for waffles. In the overhead shots, the necklace is quite prominently embedded into the cleavage of Lucy Hale. They alternate with a sideview where the string is spread across her chest. (00:01:25)
Visible crew/equipment: When Kevin crashes his bike into the trash cans near the end, as he screams, "Figglehorn!", a small part of the camera's shadow can be seen at the bottom of the screen. Then, when the camera tilts downwards as Kevin says, "Mommy," it becomes more visible. (01:19:07)
Suggested correction: I rewatched this scene, and I'm not quite sure about this one. The shadow doesn't seem to move at all when the camera does, so perhaps I was wrong here. It could be a shadow of some other equipment for all I know, or some other sort of object entirely, but it's unclear what it is to me. Maybe it's not a camera shadow.
Continuity mistake: When Adam Sandler returns to the hotel with Jennifer Aniston after their first real date they are standing by her hotel door and he has mysteriously grown a few days of stubble on his chin.
Continuity mistake: At the end of the movie, Rodrick is driving Greg to school in his van. There is a close-up showing three flyers beautifully arranged on the top of the dashboard as they are driving along, and a soft toy. After Rodrick pulls away, there is no sign of the flyers and soft toy.
Continuity mistake: Grace gets the plate with the breakfast order, consisting of two eggs, two bunches of fries, 2 slices of bacon and 3 sausages. She rearranges them to serve them in a funny face pattern, supposedly, but one piece of sausage is missing, the fries are soaked in oil and eggs and bacon appear less cooked than before. (00:02:00)
Continuity mistake: When Lucy comes home at the beginning of the movie she quickly buttons the top of her dress. While eating dinner, it is open and then buttoned again between shots.
Revealing mistake: When Wil is showing Sylvia how to shoot, and she fires, Justin Timberlake can be seen wearing earplugs. When the scene cuts, he no longer is wearing them.
Visible crew/equipment: During the attack on the town, right after Jake breaks Percy's hand to get out of the cuffs and begins kicking the wagon door we see an exterior shot of two people running and just before one does a flip, film crew is visible on the left. We see at least two people sitting in chairs, one wearing a bluish short sleeve shirt, shorts, and boots, and another in a white shirt wearing a baseball style cap. We also see a blue light coming off their equipment. (00:35:30)
Continuity mistake: When Rango is stranded in the middle of the road, he is clutching a drinking glass in his left hand. For the rest of the scene (starting from when he molts), the glass switches to his right hand.
Continuity mistake: When Cal and Emily are sitting in the classroom whilst attending Robbie's Parent/Teacher meeting, when the teacher initially writes the word 'asshole' on the board, it appears to be written differently on three separate occasions during the same scene. (00:59:40)
Continuity mistake: When Laurence asks Colin for a cigarette in the screening room, he has it between his fingers when Colin lights it, but when the shot cuts, his fingers have disappeared from around the cigarette. (00:45:30)
Factual error: When Watson is looking at the spiderweb of clues in Holmes' apartment, he is shown a newspaper article about the bombing and doctor's death. The lower left of the clipping shows a story with title "Soviet Government Money For The General Strike." The movie is set in 1891, and the term Soviet first came into use in 1905 to describe a worker's movement in Russia, but a Soviet Government didn't exist until 1917. (00:16:00)
Continuity mistake: Arthur is talking to the police, posing as Naomi's fiance: one of the cops asks, ridiculing her lie, "You had your first date at Grand Central Station?" Behind him, a white haired man in a black suit walks down the street carrying a brown suitcase. Next time the policemen are in frame, a different crowd is on the sidewalk, and only after another cut, and more of Arthur's blabbering, suitcase man reappears as if nothing happened. Even better, over half a minute passes and many totally different people...but right at the end of the scene as the policemen wave Arthur goodbye the same man, sans suitcase this time, is there again walking the same way as before. (00:19:45 - 00:20:30)
Continuity mistake: When we first see Jay there is a brown item folded next to the laptop. Camera changes and it's gone. (00:02:30)
Continuity mistake: When Reid and Kato are fighting by the pool, the beach ball falls off the chair (beside the pool) when they land in the water, but is back up on the chair in a following shot. (01:12:25)
