What's the story? Think wolf boys and sparkly vampires are a bit off the wall? You ain't seen nothing yet. Based on Stephenie Meyer's first post-Twilight book, The Host is set in a world where the human race has almost been wiped out by aliens who take over their bodies and minds. (See? Told you.) Melanie Stryder is living with her family in one of the few pockets of human resistance when an accident leads her to be captured. The aliens hope by taking over her mind they'll learn enough to overthrow the resistance and it looks like all is lost - until Melanie becomes the first human able to fight the alien presence in her mind. Slowly Wanderer, the alien she is 'host' to becomes sympathetic to the plight of humans and together they set out to save Melanie's loved ones. And Bella and Edward thought they had problems.

MAX IRONS, son of the famous Jeremy Irons, plays Jared Howe, Melanie's boyfriend. So, that's a human boy with a human girlfriend, right.

DiAne Kruger (aka The Seeker) gives good bad girl as the alien trying to track down Melanie.

? Stephenie says her absolute favourite cast member was Saoirse, even though she needed some persuading to cast her in the first place. 'I was like, "Too young. I don't want to do this teenage triangle again. It's going to be too much of a Twilight thing" Then the casting people said, "Go see her in Hanna," so I very begrudgingly did. I was sure my mind was not going to change, but I was on the phone with them before the credits were done rolling going, "OK. Sign her up. Do anything we have to do to get her."' ? Saoirse was more than happy to get her hands dirty during filming. 'I like doing my own stunts, it's more realistic. There's one stunt where I jumped off a balcony. They asked me if I wanted to do it, and apparently they were having bets I wouldn't do it. I proved them all wrong.' ? When asked what he would get rid of in humanity if he were an alien, Max Irons replied, 'Get rid of Justin Bieber! …
