Spot the difference in Hollywood hits

The film flub website called MovieMistakes.com has named its favourite continuity errors in movies from last year. Did you spot these?

1. Spider-Man 2: During the train scene, Spiderman's mask has gone partially black. We also see it when Spidey puts his mask back on. Yet when Doc takes him to Harry his mask is back to normal.

2. Kill Bill: Volume 2: When Bill is cutting the crusts off a sandwich he cuts off two, goes to remove the third - then the angle changes and he's cutting it in half. We hear him sweep the crusts off the board and see him hand the sandwich to BB. A shot or two later the crusts are back on the board and he cleans them off again to make another sandwich.

3. The Day After Tomorrow: When Dennis Quaid is briefing the President, he draws a line on a map of the United States and tells the President to have everybody south of that line evacuated. The shape of the line changes between shots.

4. Harry Potter and the Prisoner of Azkaban: When Harry drops the Monster Book of Monsters and the book chomps at him he runs backwards only a few steps and stands at the foot of the bed. But in the shot facing the fireplace there is plenty of floorspace between the rug and the bed for Harry to run backwards.

5. Secret Window: When John Turturro pins Johnny Depp against the tree with the shovel, you can see that it's a rubber shovel because it's bending around Mort's neck.
