Scoop on Stephenie Meyer's New Movie The Host —Move Over, Twilight!

Will the author's next big screen film be as big as her vampire franchise?

With only one Twilight saga flick left, Stephenie Meyer's fans are gearing up for the author's next big buzzed about movie adaptation, The Host.

But does The Host have what it takes to become as big as Kristen Stewart and Robert Pattinson's vampire franchise?

"I have no idea what people's sensibilities are, but Stephenie Meyer has a finger on a pulse of the youth of this country, of the world actually," Frances Fisher, who plays Saoirse Ronan's character's aunt Maggie in the movie, told us.

"When I started tweeting that I was doing this I was getting responses from France, South America and Russia," she said of the film's hype. "There's so many people already who are aware of The Host."

For those who don't know, The Host in an apocalyptic tale that follows Ronan's character Melanie and several others who are survivors of an alien attack on Earth. Fisher calls it, "psychological sci-fi."

"We're going to see amazing performances from Saoirse Ronan and William Hurt," Fisher teased of the cast, which also includes Diane Kruger and hot hunks Max Irons and Jake Abel.

While The Host is sure to be as big with Meyer's fans as the Twilight films are, Fisher says that's where the comparisons between the franchises ends.

"It's a whole other thing!" she laughed. "It's vampires versus aliens."

The Host is set to hit theaters March 29, 2013.
