Here are the numbers.
Halloween fell on Saturday night this year, which studios would consider the kiss of death for the whole weekend normally. Parties are a great alternatitve to moviegoing, right? God knows I was at one. Still, this didn't hurt the opening of ghoulish This Is It, the Michael Jackson concert rehersal movie. #1 at $23 million! If he had lived long enough to do the actual concert... well, who knows. Probably woulda done worse.
I was expecting Paranormal Activity to drop like a zombie with a head wound this weekend, but it's only down 22%.
Other newbie this weekend Boondock Saints II debuts at #14 and therefore does not exist. Just as well; without Willem Dafoe's overacting I'm not sure why you'd bother.
Worst-performing non-documentary Shall We Kiss debuts with $172. Not so bad, according to Rotten Tomatoes, so it must be poor marketing.
