Stephenie Meyer Impressed By 'The Host' Stars' 'Wow' Chemistry

While Robert Pattinson and Kristen Stewart eye their fourth Best Kiss statuette at this weekend's MTV Movie Awards, "Twilight" author Stephenie Meyer is revealing tidbits about another of her literary couples' on-screen heat.

We recently caught up with the writer/producer on the set of her alien-invasion adaptation, "The Host," and much like her earlier bloodsucking series, there's plenty of messy romantic entanglements here to keep audiences satisfied...and swooning. This time, it's Saoirse Ronan, Max Irons and Jake Abel who must overcome a host (heh) of obstacles to find love.

Saoirse, who plays the dual role of human Melanie and alien Wanderer, was the first to be cast in the film (due March 2013), and Stephenie said one of the big casting challenges was finding worthy leading men to act opposite the talented actress.

"This is the thing with Saoirse: When she's on the screen in a movie, you have a really hard time looking at the other actors," Stephenie explained. "Really good actors, like 'The Lovely Bones' and Stanley Tucci, he can rip your eyes away because he is awesome, totally mesmerizing. So her big thing was finding guys you could look at."

Luckily, Stephenie had at least one actor in mind, who turned out to be just what they were looking for.

"That was one of the ways Jack Abel came into this," Stephenie continued. "I'm a big fan of his, and I've always felt like when he's in a movie, he's playing the bad guy or whatever. He's not the main character, but you're always looking at him because he has that charisma. We brought him in and their chemistry was really, really great."

After finding their Ian, Stephenie and co. were left with the role of Melanie's boyfriend, Jared. "I wasn't familiar with Max Irons, but [director] Andrew [Niccol] was, and Andrew loves him. He said, let's see how he is, and the reads together were pretty wow."

"Wow," huh? We like the sound of that!

Do we smell contenders for 2013's Best Kiss statuette?
