Well, I was a tad overly optimistic about Grindhouselast week, wasn't I? Turns out not that many people want to sit through three hours of zombie gore and vehicular manslaughter. Go figger. This week, just in time for Friday the 13th, we've got loads of movies opening, most of them thrillers. It's doubtful any of them will make a top-25 list of best thrillers, but they should provide for an entertaining weekend nonetheless.

Bruce Willis and Halle Berry in Perfect StrangerPerfect Stranger
What It's About: A journalist (Halle Berry), suspecting a philandering businessman (Bruce Willis) of killing her friend, poses as an office temp and plays a seductive cat-and-mouse game with him to get at the truth.
Why It Might Do Well: Berry and Willis are big, big stars, each capable of headlining a hit movie on his/her own; and Sony has put some major marketing muscle behind this flick. Plus, Halle Berry is the most beautiful person on the planet. That isn't particularly relevant here, but I thought it needed to be said.
Why It Might Not Do Well: The reviews haven't been great, and it's rated R, which will limit its audience to adults and determined teens with cool parents and/or fake IDs.
Prediction: $15 million

Shia LaBeouf in DisturbiaDisturbia
What It's About:Shia LaBeouf stars as a troubled kid who's sentenced to house arrest for acting out in class. Having nothing better to do than spy on his neighbors, he and his friends start to think one of them may be a serial killer. It's kind of like Rear Window, except the protagonist's younger, not in a wheelchair, and, um, under arrest.
Why It Might Do Well: Going head-to-head with Perfect Stranger in the battle of the weekend thrillers, Disturbia has one crucial weapon in its corner: It's rated a teen-friendly PG-13. And LaBeouf's star is on the rise: Not only will he star in two big animated movies this year (Transformers and Surf's Up), but he's also just been tapped to co-star with Harrison Ford in the fourth Indiana Jones movie.
Why It Might Not Do Well: While he's certainly an up-and-comer, Shia's still no Bruce Willis. The biggest names besides LaBeouf are Carrie-Anne Moss (as his mom -- I don't know why this depresses me, but it does) and David Morse as the maybe-murderous neighbor.
Prediction: $15 million
