Up's 35% second-weekend drop -- allowing it to barely hang on to first place with $44.2 million, at least according to Sunday estimates -- is remarkable, placing it very nearly in Finding Nemo territory. (It's currently running around $7 million behind Pixar's highest grosser.) I am loving Up's success, not just because it's a terrific film, but because it has the least obviously commercial concept Pixar's ever tackled. (Though, as I mentioned last week, Wall-E -- which Up will now surely top -- is actually the more challenging film.)

The Hangover, meanwhile, rode great buzz and good reviews to $43.3 million, which is the second highest opening weekend ever for an R-rated comedy, behind American Pie 2. (Unless you subscribe to the ludicrous notion that Sex and the City is a comedy, in which case it's third.) If you've seen the movie, you know why it's been rapturously received. If you haven't, you should.

On the other hand, Land of the Lost was punished by reviews and a muddled marketing message, landing in 3rd place with $19.5 million. The folks at Universal tried hard to push this into the summer blockbuster A-list, but I think they would have been better off pushing it as what it is: an above-average Will Ferrell comedy. As it stands, the funny film got its ass kicked by Semi-Pro, which is sort of unacceptable.

Drag Me to Hell had a disappointing second weekend, with hopes that good word-of-mouth would help it overcome its weak opening weekend evaporating. I suppose the movie was likely inexpensive enough that its $40-million-or-so domestic final won't be seen as a total bust.

Nia Vardalos' half-hearted comeback attempt My Life in Ruins grossed $3.2 million in 9th place, which is... exactly how much Connie & Carla made in its first weekend in 2004. Oh well.
