You recognize Edward's actor because he's Cedric Diggory in the HP films. I really hope he uses his British accent. That's always how i pictured edward. Because his name sounds like Edgar i always had the picture of Edgar from the show "Edgar and Ellen" in my head for his looks. All in all it worked pretty well.
And i agree, i am most excited. mainly i wouldnt be because most book movies are terrible, except the early HP films and the LOTR series, but i liked this one a lot.
I am also incredibly curious who will play the Cullen family, mainly due to my favorite being Alice.
However i am curious as to what they will cut out or change. After all, we can't expect the movie to be exactly the same.
