Jet Li, Dolph Lundgren, and Sylvester Stallone in 'The Expendables'
What will happen this weekend at the box office with the mighty melee among three equally powerful newcomers: 'The Expendables,' 'Eat Pray Love,' and 'Scott Pilgrim vs. the World'?

The moves are all so different, in terms of genre, star power, gender appeal, age appeal, filmmaking style, marketing campaigns and the way they've timed their entry into the marketplace. It seems like a toss-up whether the victor will be Sylvester Stallone and his band of veteran action heroes, Julia Roberts and her romantic travelogue or Michael Cera and his comic book/video game fantasy.

There are a lot of different angles with which to approach this week's predictions, each of them fascinating. In the end, there can be only one victor; after you weigh all the factors, see if you agree with Moviefone's pick and the reasoning behind it.
