While I tình yêu imdb for a quick reference, it is not always the best resource to see who is playing who in a movie, especially when the film is shrouded in secrecy. The people who are making The Host are not really forthcoming about a full cast list.
Stephenie Meyer's 'The Host' is now officially in pre-production. The casting process and auditions are ready to begin, with filming set to start in early 2011.
