Corrected entry: While getting ready to leave the school for the field trip, you can see the wording on the school bus. It reads'Wilamette Valley," near where the movie was filmed in Oregon, instead of Forks, WA, where the movie is supposed to take place.
Corrected entry: In the first exterior shot of the hotel in "Scottsdale" (actually California), we see a light-post on the left of the screen with a large yellow banner reading "Scottsdale". In the next two exterior hotel shots, the banner is gone- though it is supposed to be the same day.
Corrected entry: In the biology scene where Bella & Edward are discussing why Bella decided to live in Forks, Edward says a line similar to "If you don't like the wet or cold, why did you choose the rainiest place in the continental US?" When Robert Pattinson is saying, 'Continental US,' you can detect his British accent.
Corrected entry: In the shot of the cab pulling up to the curb outside the ballet studio, which is supposedly in Phoenix, there is a light pole banner that reads Scottsdale.
Corrected entry: Edward saves Bella by standing between her truck and the careening van. He may be strong enough to not be crushed, but he's wearing ordinary shoes and has an unremarkable body weight. The coefficient of friction between his shoes and the pavement wouldn't keep him from being shoved into Bella's truck, putting a dent in it as well.
Corrected entry: In the scene where Bella is looking at Edward across the parking lot after finding out he's a vampire, she is looking at him and walking towards him. When the shot is on him, he is standing in front of the stairs/ramp, but when he turns to follow her into the woods, he is standing across from the stairs/ramp.
Corrected entry: In the prom scene, as Bella and Edward are walking around the room saying 'Hi' to people, Bella has her purse in her right hand. However, when the shot is from behind then, looking at Eric and Angela, Bella has a glass in her right hand. In the next shot facing Bella and Edward, she again has just her purse.
