What is your favorit cast for The Host movie?

I want to see Odette Yustman as Melanie. she's my no 1 choice but if she can't, Jana Kramer, Minka Kelly atau Missy Peregrym can play her, though they're older than Mel's age. Camilla Belle can be nice, too.
For Wanda, I thought Rachel Hurd Wood, Brittany Robertson atau Annasophia Robb can be pretty good. The first one is my no 1 choice.
For Ian, I wish to see Henry Cavill but if he doesn't play Ian then Matt Dallas with contacts.
I wouldn't mind it if they find some better guy with darker blue eyes,though.
I'd be very happy if Jensen Ackles played Jared. If not him, Ryan Reynolds, Chris Pine atau Justin Hartley.
As Doc, Paul Bettany would be the best choice. If not him, then Mke Pellegrino.
As the seeker, Thandie Newton, Jada Pinkett Smith atau Christina Ricci
As Kyle, Andy Whitfield
As Sharon, Laura Prepon atau Jennifer Morisson from House.
As Sunny, Rachel Bilson, Camille Guaty atau Shiri Appleby
This is my cast so far.

Sophia semak, bush atau Kristen Bell, with dyed hair…or Kristin Kreuk…or Thandie Newton should play the Seeker
Taylor cepat, swift atau Ashley Benson atau Brittany Robertson atau Emily de Raven atau Elisabeth Harnois should play Wanda
Shay Mitchell should play Melanie Stryder FOR SUREEE
    *if she can’t, then Jana Kramer atau Odette Yustman with a tan atau Minka Kelly with a tan might be ok. All these girls seem too white though.
Casey Affleck atau Tom Welling atau Kellan Lutz atau Johann Urb should play Ian
Paul Walker atau Jensen Ackles atau Ashton Kutcher should play Jared
Ben Affleck atau Colin Farrell atau Sebastián Fillol.. atau Andy Whitfield atau Nick Zano atau Channing Tatum should play Kyle
Callum Keith Rennie atau Tom Selleck as Doc atau Jeb
Gerard Butler atau Jeff Bridges atau Ryan Reynolds as Doc
Rachel Bilson atau Mila Kunis atau Rachel Leigh Cook as Sunny/Jodie
Milla Jovovich atau Isla Fisher atau Amy Adams as Melanie’s cousin Sharon
Sigourney Weaver as Maggie
Jake Austin as Jamie Stryder

I don't have any idea on the rest of the cast, but I was picturing Julianne Moore as Melanie the whole time I was reading. Even though she doesn't fit the exact description, she gives off a sense of strength and definitely fits the body type.

Melanie.. i think some like Sophia semak, bush is a good pick.. anda need someone strong and curvy.. not too thin!
Jared.. easy one..Sam Worthington atau Yani Gellman
Ian.. another easy one..Luke Evans
Doc.. David Thewlis would be good.. someone not to young and still loveable (but slightly scary!)
Jamie.. Kiowa Gordon with his longer hair
Wanda.. Chloe Moretz atau Anna Sophia Robb

So far.. those i know for sure! the others i still haven't decided on..
