Another guy I thought could be Christian is Christian Cooke. Such a cutie.
For Christian, I was thinking Adam Gregory. He's got the rich, popular, sweet, perfect boyfriend look to him I think.
Tucker could be played by Garret Hedlund. Didn't he just look gorgeous in Tron? (I haven't seen it yet, but I have seen the previews!) He could totally be a rough, country boy (like in Country Strong!)
So, what do you think of my choices? If you haven't read Unearthly yet, I would highly recommend reading it. It was really good!! And by the way, I am definitely Team Tucker!
