Look out for Kristin Cavallari, whose "Laguna Beach" launching pad has suddenly put her among the most in-demand young actresses in Hollywood. With horror flick "Fingerprints" on the way and the "Mean Girls"-like comedy "Spring Breakdown" due April 13, the ambitious blonde is pulling off a hat trick by finishing up work on a re-envisioning of a 1984 classic, "Revenge of the Nerds." "I play a sorority girl who messes with the nerds and is really mean to the nerds," the "it" girl said. "I feel kind of bad, because I love all of them. ... I love the original, and it's really been a blast. We are all just kind of young, and it's cool." Unfortunately, the new "Nerds" only has a few similar pocket-protecting lead characters -- and one of Cavallari's all-time favorites is not among them. "Some of them [are the same], but there is no Booger. I'm kind of upset about that," she said. "[The remake is] pretty different. There are similar things about it, but it definitely is different. It's a lot more updated." ...

Who knew Dane Cook had a dark side? Well, Demi Moore, for one -- and she recently revealed that the superstar comedian is going to unveil a very different persona next March in "Mr. Brooks." "I've seen only about 20 minutes of the film, but it's creepy and really intense and dark, but weirdly humorous," she said of the twisty psychological thriller about a man (Kevin Costner) with an evil alter ego (William Hurt), a conflicted accomplice (Cook) and a detective (Moore) on his tail. "Costner is like nobody has ever seen, and ... I think this is going to show a whole other part of Dane," Mrs. Ashton Kutcher professed. But when all is said and done, it might not be the men left standing. "I get to be the badass," Moore grinned. ...

After getting shipwrecked on their way to Africa, the animals from "Madagascar" finally make it to the continent in the next installment of the animated franchise. With a grin, Ben Stiller said it will make sense that Alex the lion and his buddies finally end up in Africa -- because they're actually aiming for North America. "I know that they leave Madagascar, and on the way back to New York, they get detoured on the continent," the "Zoolander" star said of the script that is "going through some changes." The script for "Madagascar 2" was delivered last week to the star and will reunite Stiller with voice talents Jada Pinkett Smith, David Schwimmer and Chris Rock. The flick is set for a 2008 release. ...

One of the most intriguing directors working today is Guillermo del Toro, whose rare mastery of fantasy and horror made 2001's "The Devil's Backbone" an under-seen masterpiece. Now, the Mexican filmmaker -- who is garnering more buzz for next month's "Pan's Labyrinth" -- is developing "3993," the final chapter in an unofficial "Spanish Civil War trilogy" that will link the three films. "It's a war that is crucial to the world, and some people think it is confined only to Spain or only to dates in the encyclopedia," the "Hellboy" director explained. "I think it's far richer than that and far more relevant to the essence of pain and war." Like the other two films, the flick will tell a ghost story with connections to the ravages of war -- but this time, it will link 1990's Spain with forgotten hostages from 1939. "I read it and fell in love with it," he said of an original script by acclaimed filmmaker Sergio Sanchez. "It was very different when I read it, but we're developing and redeveloping it for me." Del Toro hopes to begin filming the flick after his cameras finish rolling on "Hellboy 2: The Golden Army." ...

Is it too early to call Dave Grohl a legend? Maybe not, but the Foo Fighters and Nirvana member knows one thing: It isn't too early to declare that he'll never be David Bowie. "I f---ing hate rock musicians in movies. I swear to God, I hate it," Grohl said, insisting that unlike Bowie, Mick Jagger and so many others, he has no desire to be a movie star. "I get asked to do about two movies every year, and I never, ever say yes to any of them, because I can't stand it when I'm watching a movie and I see a rock musician step onscreen. It completely ruins the movie," Grohl said. Now, he's playing Satan in next week's "Tenacious D in: The Pick of Destiny," and the drummer/frontman said his fans should get a good look -- because they'll never see him in another movie. "I've been asked to do lots of other films. This is the only thing I would seriously consider doing. ... When someone says, 'Hey, you want to f---in' be the devil in the Tenacious D movie?' That's OK for a rock musician to do." ...

Does "Hostel" and "Saw" fatigue have you yearning for the days of charismatic, mask-wearing serial killers? Do you long to see Michael Myers, Freddy Krueger and Jason Voorhees linked with the 40th U.S. president? Well, get ready for "The Tripper," an old-fashioned horror flick from the proudly demented mind of David Arquette. "It's about a group of hippies who go to an outdoor music festival all messed up on drugs and then get stalked by a guy who's obsessed with Ronald Reagan," the "Scream" star said of his directing debut. "The new horror films are too torture-focused for me. I went back to an old-school slasher film. The rules are different in [those] films. You can go off with sex and violence and rock and roll and just go crazy." "The Tripper" will slash its way into theaters in 2007 with a high-powered cast of Arquette accomplices, including wife Courteney Cox, brother-in-law Thomas Jane and (as far as we know) unrelated comic-relief maestro Jason Mewes.
