Nothing can stop the power of High School Musical 3: Senior Year, which again takes the top slot at the box office grabbing $15 million in its second week, out-earning newcomer Zack and Miri Make a Porno.

This Halloween weekend saw the debut of the Kevin Smith comedy Zack and Miri, starring Seth Rogen and Elizabeth Banks as two broke desperate friends who resort to making a porn movie to earn money for their bills. Too bad Zack and Miri only managed to pull in $10.6 million, not nearly enough to push HSM 3 off the top.

Coming in at #3 is the horror sequel SAW V, also in its second week, coming in with $10.1 million this week. The Clint Eastwood drama starring Angelina Jolie, Changeling, which debuted with a limited-run last week, opened wide this weekend earning $9.4 million giving it the #4 slot.

Finishing up the Top 5 this week with $6 million was another newcomer, The Haunting of Molly Hartley, the horror feature about a girl with a horrible fate that awaits her when she turns 18.

Also opening this weekend in exactly one theater was the new Bruce Campbell campy horror My Name Is Bruce, which earned a respectable $18,000. (I mention this because I love Bruce Campbell and $12 of that $18,000 came from me, because I went to that one theater — NYC’s Landmark Sunshine Cinemas — this weekend to see it.)

Opening next week: the Paul Rudd comedy Role Models; Soul Men starring Samuel L. Jackson and Bernie Mac; the DreamWorks animated sequel Madagascar: Escape 2 Africa; the horror musical Repo! The Genetic Opera, starring Buffy alum Anthony Head; and JCVD starring action hero Jean-Claude Van Damme as Jean-Claude Van Damme (I can hear the voiceover now: “Jean-Claude Van Damme is JCVD”).
