Trivia: Right after the scene where Jacob begs Bella not to go to Italy, it shows Alice and Bella driving away in Carlisle's car; there's a glimpse of them heading down to the end of the street where a road block fence is visible. That fence is there to stop people from watching while filming.
Trivia: Director Chris Weitz did a little trick when Edward gets out of the truck after Bella's birthday party and they are arguing. They put Edward next to the camera on the right but used a double dressed like Edward in the driver's seat. When Edward gets out, it is the double and then when the real Edward steps in front of the camera it appears he got there faster than humanly possible.(Entertainment Weekly, Jan 1, 2010).
