I think the trailor is very exciting and I have a really good feeling that BD 1 and 2 are going to be the closest to the book, out of all the movies. After what Bill Condon and the cast have said, I get a real sense that, getting the full story across was very important to this director. When he spoke at CC I got the distinct impression he was very keen to portray Edward and Bella's story correctly, he mentioned about how he payed real reference to the book. This is good news to me, as I feel MR's screen plays leave to much important detail out of the other movies.
Yes, there will be added bits, there has to be, to make the movie relate better to the big screen. For example: The wolves outside the Cullen's instead of Jake going to La Push to explain to Sam. For me a good move, more exciting, as the book kind of skips over this part. Considering the desire of the pack to destroy the baby was such a big turning point in the book,I think it deserved more attention than SM gave it. The Edward tossing Jake across the room over the whole imprinting situation is a good addition, if only (very selfishly), because I think after all Jake's stunts in eclipse, Edward deserves his outburst! lol. Edward shouting "you've given me no choice", losing his temper at Bella, of course, we all know that in the book he would never distress her like this, but on the big screen; to people who are not readers of the books, it will put across the frustration and helplessness we feel from him in the book.
As for the changes in the make up and hair, yes, it is mildly irritating to me, but I can live with it. For me, the best wardrobe, hair and make up was Twilight.
In summary; I am very excited!!!!!!!!!!!!!!!!!!! roll on 18th Nov!!!
