The Host

Love never dies—it just gets replaced by vampires parasitic aliens.

The first full trailer for the big-screen version of Stephenie Meyer's post-Twilight saga, The Host, is in the wild, and if you like your Invasion of the Body Snatchers with a dash of teen angst à la Bella and Edward (hello Twihards!), this is the film for you.

E! News runs down five creepy things moviegoers can expect when The Host, directed by Gattaca and In Time helmer Andrew Niccol, invades theaters on March 29, 2013.

The Host

1. Soul Survivor: Like Twilight before it, The Host boasts two young actors who ought to appeal strongly to Meyer's massive teen fan base. Saoirse Ronan, star of Atonement, The Lovely Bones and Hanna, plays the main protagonist, Melanie Stryder, who is among a slew of humans to have their body taken over by E.T.s called Souls. Melanie ends up trapped early on inside the mind of a Soul named Wanderer, still conscious and refusing to fade away.

2. Space Invaders: Wanderer, or Wanda as she's also known, is constantly trying to maintain control over Melanie as part of her mission to locate the last remnants of free humans on Earth. However, Wanderer soon begins seeing Melanie's memories, and the two develop an emotional bond. Feeling sympathy for her human host, Wanderer seeks to sacrifice herself so that Melanie may live freely again.

3. Enter Team Jared: Before she was taken over, Melanie fell in love with a surviving human, Jared Howe, played by a hunky Max Irons, son of actor Jeremy Irons. By the time Wanderer encounters him, he's bitter about what's happened to his lover and distrusts Wanderer for what the Souls have done—until he watches Wanda comfort a dying member of his group.

4. Superhot Villain: Inglorious Basterds star Diane Kruger plays the Seeker, the head Soul responsible for finding other human survivors, including Mel's brother and boyfriend. To do this, she fuses Wanda with Melanie—only little does the Seeker realize how close the two get.

5. Uncle Knows Best: William Hurt takes on the role of Melanie's eccentric Uncle Jeb, who, as one of the first to suspect body snatchers among them, built a hideout in a complex of caves in the Arizona desert to help ensure humanity's survival. When Wanderer/Melanie arrives, he doesn't kill her because she's his niece, and instead takes her in with the hope that she might be able to help them learn how to extract the Souls from their human hosts.
