Attempting to market Funny People as a typical Adam Sandler comedy was quixotic, and as another laugh riot from the Apatow factory only marginally less so. Still, the combination of Sandler and Apatow (and, probably, Rogen) was enough to get the off-kilter, two-and-a-half-hour dramedy off to a $23 million start -- not one for the record books, but hey, not too far off the opening numbers for Apatow's Knocked Up and Sandler's Bedtime Stories. There are shades of M. Night Shyamalan in Judd Apatow, in the way that he appears to be moving from blockbuster crowdpleasers to more personal, slightly odd films that not everyone "gets."

Aliens in the Attic, hidden from critics and not really sold as any sort of event, unsurprisingly ended up with a middling $7.8 million -- a minor opening for a minor flick. The independently-distributed horror film The Collector, from some of the folks behind the Saw franchise, debuted in 11th place and $3.6 million; not great either, but probably above expectations, and perhaps an indication of how many ticket buyers are willing to see a horror movie, any horror movie, on a given weekend. (500) Days of Summer continues to do very well in limited release, with the highest per-screen average in the top 20. Next week, when the film expands to over 1000 screens, will be the real test.

Harry Potter and the Half-Blood Prince found its footing a bit in its third weekend after last week's big tumble; it won't wind up atop the franchise, but may make a run for second place. And I was glad to see Orphan hold up at least semi-respectably after a weak start. That's one summer movie that deserves better than it got.
