1. Harry Potter and the Deathly Hallows: Part 2 – Why is there snow in Hogsmeade when the trio gets there and meets Aberforth? Hogsmeade and Hogwarts are within walking distance of each other, yet there is no snow at Hogwarts.
2. X-Men: First Class – In First Class, Professor X is made handicapped in 1962 at the end of the movie. In the previous X-men movie, he was walking when he visited the girl (Jean) in the mid 70s with Magneto.
3. Transformers: Dark of the Moon – In the first scene with Carly coming up the stairs she is wearing a white cap, when the camera changes to the front view and she is holding the stuffed rabbit the cap is gone.
4. The Green Hornet – 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.
5. Source Code – This scene is repeated multiple times in the movie: usually when the main character enters the “source code” the scene begins by panning over a small pond showing a Canadian goose taking flight. However the sound editor makes the mistake of dubbing in a recording of a hen mallard duck.
6. Fast Five – The gang steal four brand new Police spec 2011 Dodge Chargers. When Brian and Dom yank the safe out, the Chargers they’re driving are older spec, with the old tail lights. Han and Roman are seen driving the other, new Chargers later in that chase.
7. The Hangover Part 2 - calls Stu “Ed” when they are fleeing from Russians with the monkey.
8. Scream 4 – In the final shot of the film, Jill’s head moves slightly when she’s supposed to be dead.
9. Pirates of the Caribbean: On Stranger Tides – Captain Barbossa’s ship has a modern Union Jack flying on the stern. The film is set in the reign of George II (1727 – 1760). The flag shown includes the cross of St Patrick, although Ireland did not become part of the United Kingdom until 1801, and the Union Jack at the time of the film would have comprised only the crosses of St George (England) and St Andrew (Scotland).
10. Thor – When the Destroyer arrives amidst the Shield agents, a coffee cup sitting on the dash of one of the vehicles spills over. The next shot it can be seen lying on its side. The reverse angle shot then shows it upright again.
