Saoirse Ronan shows off her glowing baby blue eyes in this trailer for the upcoming film The Host!

In this film, based on the book by author Stephenie Meyer, a parasitic alien soul is injected into the body of Melanie Stryder (Ronan).

Instead of carrying out her race’s mission of taking over the Earth, she forms a bond with her host and sets out to aid other free humans.

The Host also stars Diane Kruger, Max Irons, Jake Abel, and William Hurt.

Be sure to check it out in theaters on March 29th! For now, check out the trailer below!
