Open Road has released the first full-length trailer for Andrew Niccol’s (Gattaca, In Time) adaptation of Stephenie Meyer’s tween sci-fi novel “The Host.” The film stars 18-year-old Saoirse Ronan, Max Irons (Red Riding Hood), Jake Abel (I Am Number Four), Diane Kruger (Inglourious Basterds) and old-people actor William Hurt.

The Host centers on an alien invasion of human minds. Melanie Stryder (Ronan) is a young woman whose thoughts of love confuse her would-be extraterrestrial body-snatcher, making it difficult to seize control of her thoughts and keep one’s lunch.

The Host arrives in theaters on March 29, 2013.
