Not too many big changes since Tuesday, although the insanely wide release of Paramount's The Spiderwick Chronicles into 3,847 theaters, including IMAX, and with the new Indiana Jones trailer attached to it, I've decided to up my prediction closer to where I had it before I saw tracking numbers for the film (which frankly, is not painting a very pretty picture of it doing much better than last year's The Golden Compass, or even worse). Still, with the extended weekend and being the only strong family/kiddie fare even with Hannah Montana and Miley Cyrus hanging onto theaters. I'm also adding a little more onto the weekends for Step Up 2 the Streets and the Universal romantic comedy Definitely, Maybe, which have been building up buzz over the next few days and could have stronger weekends as alternatives to the action and effects movies.
