Halloween audiences split their moviegoing dollars between two very different films over the weekend.
 
The weekend champ was the documentary "Michael Jackson's This Is It," which delivered $21.3 million domestic for the three days ending Sunday, Nov. 1. The concert film, culled from behind-the-scenes rehearsal footage from the King of Pop's last weeks before his June death, has now made $101 million worldwide since it opened late Tuesday. Many box office prognosticators had projected a far higher opening weekend for what was originally a limited-run release. Sony has already extended the film's run.
 
While "This Is It" may have fallen short of expectations, the weekend's runner-up, Paramount's low-budget "Paranormal Activity," continues to exceed even the studio's wildest dreams. "Paranormal Activity" made $16.54 million over the weekend, falling only 22 percent from last weekend's total by adding more than 450 screens. "Paranormal Activity" has now made $84.78 million domestic to date  and is credited with dethroning the "Saw" franchise as Halloween king.
 
"Saw VI" finished fifth on the weekend with $5.56 million, behind "Law Abiding Citizen" ($7.73 million) and "Couples Retreat" ($6.097 million). Jigsaw's latest adventure dropped by nearly 61 percent in its second weekend, bringing its total to only $22.82 million. Yes, the "Saw" franchise keeps its budgets low, but since "Saw II," each of the films has had a lower domestic box office cume than the one before and "Saw VI" isn't likely to get within 60 percent of the $56 million total for "Saw VI."
 
Filling out the rest of the Top 10 were "Where the Wild Things Are" ($5.08 million), "The Stepfather" ($3.4 million) and a trio of box office disappointments -- "Astro Boy" ($3.035 million), "Amelia" ($3 million) and "Cirque du Freak: The Vampire's Assistant" ($2.81 million).
 
Sony Pictures Classic's "An Education" continues to be the star of the limited marketplace, taking in $505,00 in only 48 theaters for a total of $1.575 million for the Oscar favorite. Also performing well on a reduced screen load was the sequel "The Boondock Saints II: All Saints Day," which made $462,000 in only 68 theaters for the second highest per-screen average of any film in the Top 20.
