Box office prediction ... 2nd place finish
It could go either way. Unknown, Big Momma and Number Four will be released on the same amount of screens. I think Unknown might squeak out a #1 position because it looks like a redux of Liam Neeson's Taken which did well (and was a descent film). I Am Number Four should take the #2 position with the tween/twilight crowd but I think Big Momma may beat it because of Martin's still popular and mainstream audiences love a sassy talking fat suit.
