Author Stephenie Meyer is stepping outside of the Twilight realm and taking another novel to the big screen. Saoirse Ronan will star in The Host, a science-fiction story about a girl who's fighting for control of her body after being possessed by a "soul." The souls are an alien race that has come to Earth to usurp the bodies of humans. Ronan will have the challenge of portraying Melanie, the human host, and Wanderer, the soul who has invaded her.
If anyone can tackle a character with warring sides, it's Ronan, who's played complex characters in Hanna and Atonement. If you've read The Host, let me know how you think Ronan measures up.
