Revealing mistake: In the last scene where Edward and Bella are sitting in the sunny field, Edward is not sparkling. (01:52:55)
Revealing mistake: When Flynn and Maximus are fighting to get the satchel, it flies off and gets snagged on a tree branch. But you can see it goes through the branch, and not around it.
Suggested correction: If you look closely, it is very clear that it doesn't go through the branch at all, but hangs from the side as it should.
Revealing mistake: During the scene where Kirk has an "accident" in his pants, the dog goes over to lick the stain. During this seen you can easily notice some sort of beef on the stain, probably to make the dog lick it.
Revealing mistake: During the shower scene with Ally, part of Tyler's scratches disappear, due to it being makeup that was washed off in the water.
Revealing mistake: During the scene where Jennifer Lopez does not have her body pillow, she has to use her friend/neighbor as a pillow so she can sleep. The nightshirt Jennifer is wearing allows you to see the fake pregnancy belly she has on.
Revealing mistake: In the scene where Rachel McAdams goes to Patrick Wilson's office to explain why she left the bar so abruptly the night before, there are four TV monitors behind her as she does those weird charade movements. Only one monitor has a picture. The picture is of the New Jersey anchors of the job from which she was previously fired. Also, the characters in the picture never move.
Revealing mistake: Throughout the film the actors' breath is visible. This wouldn't be happening during the summer when the film is set.
Revealing mistake: At the end of the film when the two Detectives are checking the sewer for the missing button. As the male Detective is lifting the sewer, the inner sewer lid paint peels back, exposing a white color of the sewer lid. Which makes you realize the sewer is likely made of a light wood or plastic (making it easier for actors to lift lid). It is obvious the "Props Crew" didn't do a good job in painting the sewer. It is made more obvious when the female Detective tries to hide the peeling paint by very quickly sliding her hand over the exact spot its peeling. Then in the next shot the male Detective does the same, but in the corner.
Revealing mistake: When Declan and Amy miss the bus to Dublin the morning after the wedding, Amy walks out of the restaurant Poppie's Country Cooking with coffee. That restaurant is actually located in Dublin. (01:00:13)
