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: 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: 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.

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 pinned down by Moran at the arms factory in Germany, he hides behind a large artillery piece. He looks around and sees a pair of hearing protection. They appear to be modern hearing protection ear muffs, wrapped with cloth to make them look period. They have plastic clips to detach the ear cups from the metal band, which gives them away as being modern. They appear to be Peltor style hearing protection.
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: 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 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: At the airport Tim gets a red Chevy Cobalt for a rental car. It's a base model with no rear spoiler. Later he is seen driving a red Cobalt with a rear spoiler.
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: 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: Throughout dinner, Bev's steak and lettuce keep changing place randomly. Moreso, when she takes a break she puts the napkin on top of the food, but when she is back, the napkin is at the side of the plate. Between shots the cloth also ends up crumpled differently. (00:50:00 - 00:54:00)
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)
