Manny the mammoth and Diego the tiger braved the elements while returning a stranded child to his father in 2002's animated "Ice Age," but perhaps most memorable of all was Sid, the simple-minded sloth with a speech impediment. John Leguizamo will lend his voice to the creature once again for the upcoming "Ice Age 2: The Meltdown," due in March. "I get to sing in this one," Leguizamo revealed with a wry smile. "I sing a couple of rock classics in my inimitable lisp." While the tunes that will come out of Sid's mouth remain a secret ("I can't say yet until they clear it," the star said), Leguizamo revealed that the cause of his lyrical revelations in the sequel will have something to do with a newfound love. "I've got a lispy girlfriend, [voiced by] Drea de Matteo." ...

Those looking forward to the movie "Zathura" might be doing so because they assume the film is going to be a sequel to the 1995 fantasy film "Jumanji," but according to star Kristen Stewart, the two movies have little in common. "It's not a sequel at all," insisted the 15-year-old "Panic Room" actress. "The writer of 'Jumanji' [Chris Van Allsburg] wrote the book for 'Zathura,' and the only similarity is that there's a game in it, and the game sends my entire house into space and it's about my little brother trying to get us back. I'm kinda just the straight man, who comes in every once in a while for a laugh. ... If you like 'Jumanji,' hopefully you'll like this one, but you didn't have to like 'Jumanji' to like this." The film, directed by Jon Favreau, is due in theaters November 23. ... Writer/director Richard Kelly's wild imagination yielded a 6-foot-tall talking bunny named Frank in 2001's "Donnie Darko," but that was just the tip of the iceberg, according to the Rock, who stars in his upcoming apocalyptic flick, "Southland Tales." "If you think you can imagine what goes on in the mind of Richard Kelly, you can't. ... You think you [know], but you have no idea," the actor marveled. He described "Tales" as a "big, sweeping, epic thriller, dark comedy, sci-fi movie" musical that will feature him as "one of the world's biggest movie stars." Dealing with the frightening notion that "if the world came to an end, it's going to end first in L.A.," the former "Walking Tall" actor said his character "can actually foresee the ending of the world" and has to confront the ensuing chaos as the moment grows nearer. Sarah Michelle Gellar, Seann William Scott and Kevin Smith also star in the film, due next year. ...

Now that their film has become one of the biggest blockbusters of the summer, the stars of "The Fantastic Four" have begun volunteering opinions on how their characters should develop in the sequel. "I'd like to see them move onto the business of being superheroes and facing different arch-villains," Michael "Thing" Chiklis recently volunteered. "More villains and more action." Chris "Human Torch" Evans agreed, saying that in the first film "it takes us a while to get used to our powers. We're clumsy, we're testing them out, we're getting used to them, trying to get comfortable in our own skin. The second one, we could really start exploring how cool these powers actually are." Finally, Ioan "Mr. Fantastic" Gruffudd weighed in with the opinion that the second film should feature more lightweight material: "I'd like to see them in their own environment, as in walking around New York City, using these special powers in everyday life. More of those elements of it — we touched upon that in the movie, for example, Reed Richards walking down the street and he can't quite see where he's going and he stretches up and has a look over the crowd or he's able to hail a cab and get there before anyone else. Just fun little elements like that." Development of the "F4" sequel is currently under way. ...

As Steven Spielberg's high-profile next project speeds ahead with an anticipated December release, the film finally has a title. "Munich" is the official moniker for the Universal Pictures/ DreamWorks co-production, which the three-time Oscar winner is overseeing. The historical thriller is set in the days following the 1972 slaughter of 11 Israeli athletes at the Munich Olympics, as a secret Israeli squad attempts to track down and assassinate the Palestinians believed to be responsible. Eric Bana ("Hulk") stars in the film as the agent in charge of the operation. Inspired by true events, the script by "Angels in America" writer Tony Kushner is said to be based on a number of sources, many firsthand. ... Another day, another video-game movie announcement: following on the heels of everything from "Max Payne" to "American McGee's Alice" to "Dungeon Siege," the hit game "God of War" will be developed into a feature film by Universal Pictures. Producers Charles Roven ("Batman Begins") and Alex Gartner ("Barbershop 2") will oversee the project, based on the "interactive movie" game that has been a top-10 bestseller since its release in March. The game (and now movie) portray such enduring fantasy creatures as Medusa and the Cyclops while telling the tale of a merciless warrior in ancient Greece. The production of the film is expected to occur in conjunction with a sequel to the photo-realistic game. ...
