Owen Wilson's sandy blond hair and mischievous grin make him look like a lot of things: beach bum, slacker, maybe even a wedding crasher. But would you buy him as a prehistoric caveman? "A caveman, yes, but kind of like the caveman who worries he's getting too much sun and has modern dilemmas in a caveman setting," Wilson said recently, describing the tenor of the still-untitled comedy in which he'll star for "Groundhog Day" writer/director Harold Ramis. "It's a study, like Mel Brooks' 'History of the World: Part I.' It's kind of like looking back on the dawn of man, but making it into a comedy." ... After one extraordinarily rambling (and equally funny) adventure last year, Harold & Kumar finally got their hamburgers. Now it looks like they'll be supersizing their adventures. "We are actively working on [a sequel to 'Harold & Kumar Go to White Castle']," star Kal Penn excitedly volunteered on the red carpet of the recent MTV Movie Awards. "The writers are writing; this time we go to Amsterdam. That should be a good movie." ...

Lately, Lindsay Lohan has spent her days dodging paparazzi-filled cars and her nights allegedly partying in places she's never been to, alongside people she's never met. With "Herbie: Fully Loaded" now behind her, she hopes to make more valuable use of her time. "I don't even know if I should say this, but I'm trying to go to Iraq right now," Lohan revealed. The actress/singer is making plans to deliver aid to the less fortunate in the war-torn region, and will be bringing along cameras for a potential television series. "It's very dangerous right now, so we're seeing what's going to happen. ... I'm going to visit the hospitals; that's something I really want to do. I like to be very involved with giving back. And I have brothers and sisters, and I love kids. So my charity, basically, I want it to be for underprivileged kids." If you've already tuned in to their TV show "Meet the Barkers," then you're familiar with Blink-182 drummer Travis Barker and his actress/ former Miss USA wife, Shanna Moakler. In case you're wondering what the lovebirds are up to on a given Friday night, Travis is happy to name a few of their intended date movies. "I want to see 'Lords of Dogtown,' that looks really good," the tattooed reality star offered. "And I want to see the jeans movies, 'Sisterhood of the Traveling Jeans' (sic). That's the sh--. Just so I can say I did." As for Shanna, she'd rather be in movies than watch them: "I'm going to New Orleans to shoot 'Big Momma's House 2,' " she said. "It's a small part, but it's going to be fun." ...

Hollywood has already remade nearly every film in the Michael Caine canon, and the legendary actor says he couldn't be happier, because they keep giving him more work. "I'm trying to do a remake of 'Sleuth' now," revealed the actor, who would appear in the update of his 1972 film, much as he did a few years ago with "Get Carter." Caine would play an older character in the film, and the younger version of himself would be played once again by the star of the recent "Alfie" remake. "[It will be] with Jude Law, written by ['The French Lieutenant's Woman' writer] Harold Pinter," Caine added. "It could be interesting. It might happen; we only finished the script last week." ... Jessica Simpson may not possess the right hair color to play Wonder Woman, but that doesn't mean she can't someday portray a comic-book heroine. The singer and "Dukes of Hazzard" actress shot some sample footage for a big-screen adaptation of the cult Marvel title "Mort the Dead Teenager," which tells the story of a slacker teen who reluctantly returns to haunt his old friends. Now, according to Marvel Studios chairman and CEO Avi Arad, plans are moving forward on a full-length movie. "We absolutely love Mort, and these eight minutes, unedited, tells you why we should make the movie," Arad said of the teen-oriented film, which will have a "Beetlejuice" sensibility. "This guy [who directed the test footage] should make the movie, but he's a first-time director. He got Jessica to do it. He basically wanted to show the tone and his understanding of the Mort idea, and he nailed it. Everyone who sees it loves it." ...

George Romero invented the modern zombie movie nearly 40 years ago, and with this month's "Land of the Dead," his franchise returns to life. By now, the 65 year old should be getting tired and out of touch, but somebody forgot to tell that to him. "I'd love to make 'Diamond Dead,' " he said. "It's a rock-and-roll zombie comedy [with famed composer] Richard Hartley -- the music's written." The horror film will tell the tale of a woman enlisted by Death to kill 365 people in one year. To dispatch her victims in one fell swoop, she reunites a dead rock band and takes aim at its audience. "Asia Argento had agreed to be in it, and it looked like it was going to happen," Romero remembered of the temporary stalling of the project. "It was just one of those that never happened quickly enough, and ['Land of the Dead'] came along and I had to do it. I'm hoping we can get back to that, it's a project I really love." ... If "Scary Movie" made you laugh at your fears, and "Not Another Teen Movie" made you giggle over the clichés of the Freddie Prinze subgenre, then you'll be excited to hear that production has begun on a film that plans to give the same satirical skewering to romantic comedies. Alyson Hannigan ("American Pie") and newcomer Adam Campbell will star alongside comedy veterans Jennifer Coolidge and Fred Willard. Penned by "Scary Movie" co-writers Aaron Seltzer and Jason Friedberg, the as-yet-untitled film will lampoon genre touchstones that have played out ad nauseam in everything from "Two Weeks Notice" to "How to Lose a Guy in 10 Days" to a hundred other movies you once enjoyed but can now barely differentiate from each other. The film is aiming for a 2006 release, and one can only hope it will open opposite something starring Meg Ryan and Hugh Grant. ...
