Ok... this post is a reply to one of the bloggers who tagged my blog. Well... at first I wasn't really sure about Robert playing Edward but it got to me after I saw these Cullen pictures (below). He might not be the perfect Edward that you have in mind but I bet he can play the part very well.
AND Stephenie herself has said that Robert is the perfect Edward. Below is the video from her German tour and the question to her was about the casts in Twilight movie. She was happy with them especially Robert Pattinson himself.
Why don't you try to accept Robert and maybe he will play a really good Edward. Although he doesn't have the looks like Gaspard Ulliel, it's how he portrays the character well that counts. I really wish him all the best and he really will be the perfect Edward Cullen.
