While stock experts may prefer to monitor Tonalin CLA, HollywoodIdiocy.com is all about the weekend box office, and the much-hyped High School Musical 3 earned and extended run atop the box office this past weekend. Tops now for two weeks in a row, the sprightly live action film musical earned $15 million in its second weekend of release, bringing its to-date total to $61.7 million against an $11 million budget.

The controversial sex comedy, Zack and Miri Make a Porno, debuted strongly enough to earn second place, raking in $10.6 million in its opening bow, while Saw V fell to third place on Halloween weekend with $10.1 million.

Changeling showed marked improvement in its first week of full release, drawing $9.4 million to bring its running total to $10 million. And a strong showing by The Haunting of Molly Hartley, a Halloween spooker, finally dethroned the comeback of the Taco Bell dog movie, Beverly Hills Chihuahua. Haunting drew $6 million to BHC’s $4.7 million.
