Stephenie Meyer's The Host Book to Movie?

Okay it's been announced ( a while ago) that Stephenie Meyer's book The Host is being turned into movie. Who do you think would be good for the cast line up?

I just started reading the book, I am on chapter 25. Please don't spoil it for me.

My cast line would look like this (and why):

Wanderer/Melanie - ANNA KENDRICK She's perfect look, young and with a fresh face. Her acting isn't terrible either.

Jared - Jensen Ackles He absolutely has to be Jared. He's got sharp features. I can't help but love and hate Jared's character at the same time. He's got to be someone who can portray strength but also passion, and this actor does it well.

Jaime - This one it tough...I think you'd have to go on a search for this one. I can't find any one I like to play Jaime. Not to mention the varying ages of this character in the book.

Ian - Shia LaBeouf He's handsome and has that comedic timing but can still do drama. Which is what I think about when I think of Ian.

Jeb - Jeff Bridges...I know I know he's famous but he plays a great crazy.

The Seeker (oh you know which one I am talking about) - Kelly Hu She was great in X2, I think she could pull it off.

I am curious to here what others have to say about this.

Later.
