No surprises in the top spot: Monsters vs. Aliens handily took the weekend, its $58 million gross comparing favorably with previous Dreamworks Animation openings -- especially considering that it opened in March. The only Dreamworks films to open stronger bowed over the summer or during the holiday rush, and Monsters vs. Aliens had the third highest spring opening ever. It has no new family-oriented competition next week, so it should hold up pretty well at least until Hannah Montana comes along on April 10th.

I'm also pretty impressed with the $23 million second-place start for the non-event that is The Haunting in Connecticut -- those who've seen it know that it's a low-key, mournful little horror film that barely even merits the "horror" badge. It's the year's second-best start for a horror offering, and it should hold up better than Friday the 13th, which holds the title. Everyone be impressed with Lionsgate's ability to launch a horror flick.

Also, everyone point and laugh at Fox, which vomited the John Cena/Renny Harlin collaboration 12 Rounds onto 2,300 screens and has $5.3 million to show for it. That's about $2 million below 2006's Cena vehicle, The Marine. WWE Films has yet to have even a moderate hit without The Rock in it, and The Rock -- excuse me, Dwayne Johnson -- has long gone his own way.

A bit more, and the full top 10, after the jump. Glancing at the holdovers, I Love You, Man held up well, Knowing respectably, and Race to Witch Mountain got shellacked by Monster competition. And just below the top 10 we'll find a semi-wide release of one of those niche films that you've never heard of but that unexpectedly pops up near the top of the box office once in a while. It's called The Cross: The Arthur Blessit Story, and it appears to be a doc about an evangelist who carries an enormous cross with him as he travels the world preaching the gospel. It took in just over $300K on 221 screens.

Oh, by the way, apropos of nothing: anyone care to guess what the top two grossers of 2009 to date are? Would you believe Paul Blart: Mall Cop and Taken? And it's not even clear that Monsters vs. Aliens will break #3.

Next week sees Adventureland and the eponymous reboot of the Fast & Furious franchise. The last entry sort of flopped three years ago, dropping 50% off its predecessor, so we'll see what happens.
