1 ‘Saw 3D’ The seventh and final installment of these smart horror movies is the one that most of us will see this weekend — because, really, can you resist the idea of bloody power tools coming out of the screen to scare the Halloween out of you?

2 ‘The Girl Who Kicked the Hornet’s Nest’ This is the one that most of us should see this weekend. The first two installments in this Swedish trilogy of Stieg Larsson adaptations were so good that they hardly need the Americanized versions that will start coming out next year.

3 ‘Welcome to the Rileys’ James Gandolfini plays a guy on a business trip to New Orleans who “seeks salvation by caring for a wayward young woman” played by Kristen Stewart.

4 ‘Paranormal Activity 2’
Micah and Katie are being tormented by a demon again — and this time, it wants a word with their dog and baby.

5 ‘Hereafter’ Matt Damon sees dead people in Clint Eastwood’s latest.

6 ‘Red’ Bruce Willis might be playing a retired CIA agent at this point, but at least he’s “Red” — as in “retired, extremely dangerous.”

7 ‘Jackass 3D’ Johnny Knoxville et al. are back to trying to kill themselves, usually while in underwear and now in 3-D.

8 ‘My Soul to Take’ Wes Craven’s new flick tells the story of a serial killer who returns to his hometown to kill the seven children born on the date he supposedly died.

9 ‘The Social Network’ If you believe Aaron Sorkin’s story, Facebook founder Mark Zuckerberg (played here by Jesse Eisenberg) didn’t actually have that many social skills in the real world.

10 ‘Let Me In’ Chloe Moretz stars as a bloodthirsty tween vampire.
