Stephenie Meyer’s little Twilight story hogs a lot of the spotlight these days, but the author isn’t all about sparkly vampires and scorned werewolves. Meyer also took a spin down the sci-fi road with The Host, and now big names from both The Hunger Games and HBO’s Game of Thrones are being looked at as male leads for the extra-terrestrial possession adventure.

Writer/director Andrew Niccol is getting ready to get to started on the adaptation of Meyer’s The Host, as the Twilight Saga gets ready to wind down, and all eyes are on the contenders for the two male leads that will play opposite Saoirse Ronan, who has already secured the part of main character Melanie.

Judging from the news coming from Variety, the battle could be a hot and heavy one because none of these guys can be considered slouches. Liam Hemsworth (The Hunger Games), Kit Harington (Game of Thrones), Jai Courtney (Spartacus: Blood and Sand), and Max Irons (Red Riding Hood) have tested for the part of Jared, Melanie’s boyfriend. Dane DeHaan (In Treatment), Thomas McDonnell (Prom), Augustus Prew (The Borgias), and Jake Abel (The Lovely Bones) tried out for the role of Ian, a guy with a serious attitude that eventually falls in love with the alien inhabiting Melanie’s body.

I’ll give you a quick info-dump in case you’re a stranger to The Host. The Earth has been invaded by aliens and people are used as hosts for them. Melanie is captured and becomes the vessel for an alien named Wanderer but she doesn’t go down without a fight. Melanie’s resistance and Wanderer’s curiosity soon results in an odd form of alliance between the two.

And then things get messed up by tossing in yet another love triangle. Think it was screwy to have a girl torn up between deciding on a vampire or werewolf? Wait until you see two guys fight over two women that inhabit the same body.

Even with the love story tucked in there, The Host sounds like a great dystopian-style adventure showing a fight for survival on the landscape of a defeated Earth, so it could be worth checking out.

It’s still early so things could change, but The Host is expected to arrive on the big screen on March 29, 2013.
