Gone Girl Casting

I've become completely consumed by Gone Girl.  I'm not done yet, I've got about 1/3 of the book left and I am DYING to know what happens!  (I'm actually listening to it on audiobook while I run, which is the first time I've tried doing that.  I would recommend it, by the way.)  I know a movie is going to be made of it, and I can't stop picturing the cast in my mind while I listen.  I've heard that Reese Witherspoon is producing it but not necessarily starring as Amy.  Is that what you've heard too?  I wouldn't be opposed to her playing Amy, but here are my first picks:

Amy Adams.  I LOVE her! She is versatile and I think could play the "Good Amy" and "Real Amy" roles well.  I picture her with blonde hair for this role.

Charlize Theron.  I think she has the perfect look for this role and can definitely be versatile also.

Ok.  Now for Nick.  He needs to be good-looking and all-American.  Here are my favorites for this role:

Bradley Cooper.  Everyone loves him, right?  Can't really go wrong with him.

Jake Gyllenhaal.  It's no secret that he's incredibly good looking and I also think he's a great actor.  And how cool would it be if his real-life sister played his on-screen sister.

That brings me to Go, Nick's sister.

Maggie Gyllenhaal.  I really love her, she's such a great actress and is pretty much the only person I can see in this role.

If I can't have Maggie, I think Rashida Jones could make a good Go.  Maybe.

The other character I keep picturing is Andie.  She has to be much younger and I think she needs to be able to pull of the ditzy thing.

Lucy Hale.  Is is MUCH younger, maybe too young?  She's 23, but usually plays teenagers.  I think she's got the perfect look though.

Minka Kelly.  She has the ability to play this role, she can act sweet but in a bad girl way.

That's about all I've got right now.  If you have read this book, who do you picture for each character?  I'd love to hear more opinions!
