Beautiful Creatures Cast

Beautiful Creatures is going to be a movie we know that for quite a long time but it's getting real now because we have our Lena, Ethan and Amma.

Lena - Alice Englert 

Ethan - Jack O'Connell 

Amma - Viola Davis

First I don't have an opinion about Amma I can't quite picture her. But I think Viola Davis can be good.
I'm really happy by Lena choice. Alice Englert has a really beautiful face and I think once she'll dye her hair black she will be a great Lena.
But i'm really sceptical about Ethan... Well I really like this actor but I saw him in Skins and now... I don't know I just can't picture him as Ethan. I hope i'm wrong and he'll be an awesome Ethan !

I need to say that i'm really worried by this adaptation. I'm deeply attached to this series because it's one of the first YA series that I read in english and Lena is one of my favorite character ever. And sometimes I just want to say : Stop turning all the books into movies !
Yes it can be good to see movies adaptations based on books and I love a lot of them but... I just don't know what to think about it because I must confess that I hate when it become a phenomenon and I'm really protective and don't really want to share sometimes when I loved a book. I know it's quite paradoxal because it's the point of my blog : to share ! I just can't explain it... For example I'm going to see The Hunger Games movie in March but i'm not that excited because I'm worried...
I think I need to stop i'm being too much paranoid...

EDIT
Mrs Lincoln -Sarafine - Emma Thompson 

 Wow I can't believe that she is going to be in Beautiful Creatures movie. She is such a great actress ! But did I miss something? Why Mrs Lincoln and Sarafine should be played by the same person? Anyway I can totally picture her for Mrs Lincoln but not really for Sarafine...
