Continuity mistake: In the dance contest, Pat's shirt is tucked in at the beginning. During the "Fell In Love With a Girl" portion his shirt comes totally out. Subsequently his shirt is tucked in again.
Plot hole: Ruthven is apparently bitter that he has been denied his chance of becoming an immortal vampire after Clara steals the map from him, which is why he attacks Eleanor. But why doesn't he just go to the island anyway? You don't need to be invited - Clara, Eleanor and Frank aren't. Having been there once, it seems highly unlikely he can't find it again - he's a naval captain, so navigation and observation are major professional skills for him. And it isn't hidden or magically protected - the local boatmen know where it is and are prepared to take people there, although they won't set foot on it themselves. He could quite easily have gone there without the map, entered the shrine and been turned into a vampire if that's what he wanted.
Continuity mistake: When the Once-ler is drifting down the river in his bed, he puts his foot in the water, which makes the bed turn. When he puts his foot back onto the bed, it is dry and so is the bed sheet.
Continuity mistake: When Alice knocks over the giant Licker in the Rolls-Royce, the driver's side of the car remains completely undamaged. Unlikely, but for the rest of the chase there are four giant scratches across the rear of the car. (00:51:10 - 00:52:05)
Continuity mistake: At the end of the movie when Kwon says he will take Bobo down if he ever breaks the law again, Bobo empties his glass of whisky. In the next shot when Bobo puts the glass down, it's half full. (01:25:30)
Deliberate mistake: Manny refers to the pirate rabbit as the Easter Bunny, even though Easter never existed in prehistoric times. (00:33:55)
Suggested correction: And mammoths didn't hang out with sloths and smilodons either. It's creative license.
Continuity mistake: When Joseph Gordon-Levitt is shot by Emily Blunt with rock salt, he is hit in the right shoulder. In the next scene he is having his left shoulder treated. The porch swing and chair are now on opposite sides from other scenes too - the whole shot is flipped.
Continuity mistake: When Peter falls through the roof and lands in the wrestling ring, the planks on his body suddenly disappear.
Continuity mistake: At the end, when Bella is thrown into Edward, she is wearing shoes with a heel, but a few seconds later she is wearing regular boots. (01:32:50)
Character mistake: As Bruce Wayne is researching the jewel thief, the word "Heist" is spelled "Hiest" in a newspaper headline. (00:15:45)
Factual error: In the beginning scene in the locker room, Taylor brings up his Glock and calls it the "Glock 19", however a shot shows the pistol's trademarks, displaying it as a Glock 22.
Revealing mistake: When Aladeen tries to jump the fence of the UN, a hearing device is seen in actor Sacha Baron Coen's ear.
Continuity mistake: In the movie Band Camp, which takes place in 2005, Jim's dad tells Matt Stifler that Michelle is pregnant, so Jim's son should be 7 years old in this film, not 2.
Continuity mistake: When Dex is being interviewed in the park, he is holding the basket of baby kittens that he rescued. He is never shown handing the basket to anybody else, but just seconds later, as everyone leaves and Dan arrives in the scene, the basket of baby kittens has suddenly vanished. (00:04:30)

Character mistake: In the middle of the film Candice answers Michael's phone and says "Michael Atwater's phone how can I help you." At the end of the movie during Candace's family reunion Michael makes an announcement and says his name is Michael Hanover.
Continuity mistake: Evan arrives at Costco in a polo shirt. He sees the body, then cue music, and you see him driving away in a shirt and tie. (00:09:45)
Suggested correction: I think the shirt and tie scene is a jump forward to Goosman's funeral.
Other mistake: Jack takes the moonshine to Floyd Banner and sells 200 gallons @ $5 a gallon, ie. $1,000. When he gives the money to Forrest he tells him it's $2,000 minus his commission.
