Books v.s. Movies

How did you picture the characters in the books and how did they change in the movies?
Any other differences with the books and movies?

Thoughts? Opinions? Do tell!

I don't really remember what I imagined them to look like. It's been such a long time since I've read the books and now that Twilight is so huge, it's hard to picture anyone else but the actors and actresses. I'm sure I pictured them different at one point but it's been so long.

Don't get me wrong, I'm a big fan of Kellan Lutz and Taylor Lautner but I pictures Emmett and Jacob different. I pictured Emmett this huge monster of a man and same with Jacob, but I also picture Jacob as a white guy.. which makes no sense since it clearly says he's Indian.

Oh! And the Masters. I did NOT picture them as that but I wouldn't change them for the world now. I can't even remember what I pictured them as but I remember being shocked when I saw what they looked like. I think I didn't picture them with long hair but I really can't remember.

For the most part though, I can't remember the other characters.
