Other mistake: Neither Edward nor Bella are sparkling at the very end of the movie in the sunny scene in the meadow of purple flowers, as the vampires are supposed to. (01:40:00)
Other mistake: In this movie, Gandalf looks older than he does in his grey incarnation in Lord Of The Rings: The Fellowship Of The Ring. However, this takes place before the Lord Of The Rings trilogy, so he should look younger, or the same.
Other mistake: After the song "How Bad Can I Be?", the camera is looking at the animals with 5 trees and the tree cutting machine behind them. As the machine reaches the 4th tree, the tree doesn't fall. (00:56:40)
Other mistake: Big animals are small and small animals are big on the island, but Alexander has fireflies in a jar at his treehouse. If animal sizes are reversed on the island, the fire flies should be very large, similar to the bees that show up later in the movie.
Other mistake: As Jim and Cindy Green and their "son" Timothy enter a hospital room where Uncle Bub lay dying, the clock on the wall shows 7:39. Two minutes later, the clock still shows 7:39.
Other mistake: Aladdin slices off one head of the monster in the tomb. The body spurts copious amounts of blood and the severed head even bounces on him repeatedly, but Aladdin's shirt is immaculate afterwards. (00:04:40)
Other mistake: Throughout the saga, blood has been shown as essential for vampire's healing factor, and Selene herself used her blood to heal people. Somehow, this time around neither her or her pal David think in any way of this basic fact, making a complicated trip to the vampire doctor necessary, who simply feeds the vampire kid some blood, the very first thing any vampire would do to regain strength.
