It may have seemed like an "off" week by summer standards in terms of releases, but two debuts and two strong holdovers meant that four films grossed $20 million or more, which is rare for a non-holiday weekend. The top dog, surprisingly, turned out to be The Proposal, which rode a genial marketing campaign and a set of sneak previews to $34 million dollars -- Sandra Bullock's best opening weekend ever, by far. (Related question: did Bullock "open" this movie? I'm inclined to think not, though it's a perfect role for her.)

Year One is a bit tougher to read. Certainly with the Cera/Black/Ramis combination, it was expected to open bigger. Generally poor reviews didn't help; I haven't seen the film, so I'm a bit handicapped in the analysis. If I had to guess, I'd say that people saw it as a bit of a novelty item. Silliness can be hard to sell if it's not low-brow.

But the weekend's real story, I'd say, is once again The Hangover, which stuck around in second place after dropping less than 20% in its third weekend. It's hard to find a precise analogue for it at this point; Box Office Mojo stretches with "R-rated summer comedy breakout," which category it will dominate after it speeds ahead of Wedding Crashers in about two weeks. The movie did add nearly 200 new screens; still, when people talk about word-of-mouth giving a movie legs, this is what they're hoping for.

Meanwhile, Up is now pretty much running neck-in-neck with Finding Nemo for the title of highest-grossing Pixar release. It will be close.
