Factual error: In the scene in Kono, one of the child soldiers is seen with a Game Boy Advance SP, which was released in 2003, but the movie takes place in the 90's.
Factual error: During the Marshall-Xavier game the announcer refers to Xavier as the "Pirates", but Xavier's nickname is and was "Musketeers".
Continuity mistake: When Leonidas, and presumably all the other Spartans, use their spears to clear their shields of arrows after the arrow shower from Persian archers, the tips of the arrows are still visibly left on all their shields. In the next shot, when the Spartans regroup for the Persian cavalry charge, the arrow tips are gone. (Granted, this is a highly stylized movie based on a comic book, but that does not change the fact that this is a continuity error.)
Continuity mistake: In the cafeteria scene, when Britney sits down and the other girls move away, there is rubbish on the table and a can of Pepsi, but after looking at her phone message she stands up and the table is completely clear of the rubbish.
Plot hole: The whole plot of the first "Brother Bear" was that Kenai had to go to that mountain to become human. But at the end of this movie, the spirits were about to change Kenai back into a human in the middle of a cliff, which makes the entire first movie completely pointless.
Continuity mistake: In the fight scene at the party, Jake gets hit over the head with a bottle and he has blood on the top of his head. It changes constantly throughout the fight. It disappears totally when the fight is over. He has no blood anywhere on his body.
Continuity mistake: The cookie Calvin rubs all over his body only has raisins on the top left of the cookie. When the grandfather picks it up they are neatly in the center: not the same cookie.
Continuity mistake: After Jon tells Garfield that he is going to ask Liz to marry him, Garfield knocks Liz's picture to the ground and we hear glass break. When Jon comes back into the room to turn off the stereo, the picture is suddenly back up on the table without him replacing it.
Character mistake: When they arrive at the motel, the mother says that the grandpa is in room 13, but when he opens his door it is room 208.
Continuity mistake: Nick goes out of his office and to Bristol's desk. Bristol starts standing up. Camera angle changes to Nick then back to Bristol. He starts standing up again. (00:40:40)
Continuity mistake: When Ryan Reynolds is between the two hospital beds, preparing to pull the plugs, there are three wires he grabs to our left (two white and one black). He yanks all of them out (along with another white one to our right) and no plugs remain in the red outlet cover on the wall. But in close ups, as the other agents are banging on the door, we see the lone black wire is still plugged in. (01:40:15)
Continuity mistake: Cecilia and Raymond are on the end of the dock and Raymond turns around and runs. Cecilia then says her line, turns around and runs. In the next shot the two girls are running towards the end of the dock. You can see Raymond running towards them but Cecilia is gone. She should be in the scene running the same way. (01:28:05)
Continuity mistake: In the morgue scene, the coroner states that Elizabeth Short had a wound inflicted on her right hand, but then in the pornography scene, she grips the bed post with her left hand.
Audio problem: Near the end when Drake is playing Hollywood Girl and gets into the bridge (the steady drum beat part) you can obviously tell he's mouthing the words.
Continuity mistake: When Jackson realizes his truck is going into the pond, Martha starts walking forward. Next shot, she is still standing still.
Continuity mistake: When Andy and Miranda are in the limo in Paris, they pull up to the curb and there is a bunch of press waiting as Miranda opens the door. However, when the shot changes, it is not the same group of people - in particular, there is a balding photographer who should be standing right there but is nowhere to be seen. It all happens too quickly for that much change.
Continuity mistake: Hugh Jackman puts a tan vest on twice in the scene when we first meet his wife.
Continuity mistake: When Jerry and the Dr. are talking in the tent the first night on the way to the mountain, the Dr. shows Jerry a notebook with a picture of his wife and son. Jerry hands the notebook back twice in a repeat of the same shot.
Continuity mistake: In the canoe ride down the hill, the oar outside the left of the canoe makes the canoe turn right to avoid the tree. Scraping the group to the left would cause the canoe to turn left.
Continuity mistake: Near the end of the movie, when the helicopter sets down on top of a tall building, the registration mark of the aircraft changes noticeably several times, from G-ORMA to G-ICSG and back again.
