The Host

Earth is invaded by alien “souls” who take over the bodies of humans, but at least one of them (Saoirse Ronan) finds that her human counterpart refuses to die quietly. The two personalities wind up working together to find the kid brother (Chandler Canterbury) and boyfriend (Max Irons) the human half of them left behind. Adapted by writer-director Andrew Niccol from the novel by Twilight's Stephenie Meyer, the movie is highly entertaining—but mainly as an unintentional comedy. It's like a Mad Magazine parody: “If Stephenie Meyer had written Invasion of the Body Snatchers”—an instant camp classic. Poor Ronan carries on hilarious arguments with herself in voice-over, and her two-in-one character is torn between three—Irons, Jake Abel and Boyd Holbrook—who are all but indistinguishable.
