Halloween audiences picked beats over blood this weekend, pushing Michael Jackson’s This Is It to the top spot, while horror phenomenon Paranormal Activity scored a strong second-place finish. With a $21.3 million domestic gross, This Is It raised its worldwide total to a massive $101 million that easily breaks the record for a concert doc, though it falls far short of the $250 million that concert promoter AEG reportedly predicted. Even so, the performance was good enough to convince distributor Sony (which acquired the pic for a mere $60 million) to announce that the concert pic will remain in theaters at least until Thanksgiving.

Still beating expectations in its third wide-release weekend, the sleeper hit Paranormal Activity dropped just 22 percent for a $16.5 million haul. At $84.8 million total after six weekends, the surprise smash is now the year’s highest grossing horror movie. Rounding out the top five are holdovers Law Abiding Citizen ($7.3 million), Couples Retreat, ($6.1 million), and Saw VI ($5.6 million).

The weekend’s two other newbies both had lukewarm receptions in wide release: The Boondock Saints II: All Saints Day made $0.5 million at 68 theaters, while Gentlemen Broncos earned $10,000 at two sites.
