the host

let me just clear the air. i don't hate everything by stephenie meyer. i liked her book "the host". hopefully, she won't write a sequel to it because i loved the way it ended.
why did i like the host? hmm...let me see...the plot was very engaging and was cool twist on the whole bodies-being-invaded-by-aliens things. and it had a pretty good love triangle-thing going on. and i loved the characters, especially the two romantic interests(jared and ian). why? because they were really realistic and easy to relate to...and nothing says romance like giving a girl Cheetos(note: i'm being serious)
since i'm bored, i decided to cast the host. here goes...
melanie: carey mulligan. she would be so perfect. not even kidding. look her up if you haven't heard of her
ian: i was thinking jj fields...he was so great in northanger abbey...or maybe james d'arcy. also a good actor. or maybe even jake gyllenhaal(but he might be too old).
jared: rupert penry-jones. no questions asked. or maybe dominic cooper(from the duchess/mama mia)
jamie: thomas sangster. most adorable kid. ever.
uncle jeb: not sure....
the seeker: sophia myles. she's pretty in a very cold way. or christina ricci.
kyle: i can only see hugh jackman playing him.
doc: hugh laurie. i know it's so stereotypical, but it'd be so good. hugh laurie is really talented.
this all i have cast wise. what do you think?
