With "Spider-Man 3" on the verge of release and the "Fantastic Four" sequel right behind it this summer, attention is shifting to Marvel's soon-to-shoot comic adaptation of "Iron Man." With the studio staying tight-lipped, the biggest question on geek minds these days is who star Robert Downey Jr. will be battling. So, ladies and gentlemen of the jury, we'd like to present Exhibit A. "I play Obadiah Stane," a shockingly bald and bearded Jeff Bridges told MTV News this week, finally revealing his character in the movie. "He's kind of a mentor [to Tony Stark, a.k.a. Iron Man]." According to the classic comics, Stane is a billionaire industrialist who excels at manipulating his opponents and eventually gets close enough to Stark to pull a hostile takeover on his company, Stark International. If director Jon Favreau stays true to the story line, Bridges will eventually build his own Iron Man suit, become Iron Monger — the movie's villain! — and drive Stark to alcoholism in the sequel. "[Stark] is a fella who is the son of a very famous arms dealer," Bridges said of the script. "He gets captured and he builds this incredible suit. ... He's kind of like a superhero, but he's based pretty much on reality." Bald dude Bridges begins shooting soon, alongside Downey, Terrence Howard and Gwyneth Paltrow. Bridges will also be heard — but not seen — in the animated penguin flick "Surf's Up," which opens June 8. ...

"What the hell am I doing?" laughed a forgetful Adam Sandler this past week when MTV News asked what the in-demand star had going on beyond the summer blockbuster "I Now Pronounce You Chuck and Larry." As it turns out, the foulmouthed funnyman will be playing an Israeli man, Sandler revealed. "He's a soldier, and he fakes his own death in a fight so he can come to New York and become a hair stylist." Penned by the comedic wonder team of "The 40-Year-Old Virgin" writer Judd Apatow and Triumph the Insult Comic Dog alter-ego Robert Smigel, the flick will reunite Sandler with his old friend Rob Schneider and has a title that the comedian couldn't even say without taking on his character's accent. " 'You Don't Mess With the Zohan.' I'm doing that in July," he laughed. Sandler is also producing the movie, which will film in New York and L.A. for a summer 2008 release. ...

Fast-rising star Rainn Wilson (TV's "The Office") is the latest actor to join the impressive cast of "Juno," director Jason Reitman's follow-up to "Thank You for Smoking." The dark comedy, which stars Ellen Page ("X-Men: The Last Stand") as a teen faced with an unplanned pregnancy, also stars Jennifer Garner, Allison Janney and "Arrested Development" duo Jason Bateman and Michael Cera. Wilson has been cast as a sneering drug store clerk who dispenses an EPT test, licorice ropes and a guilt trip to the conflicted teen. The flick, which is currently filming in Vancouver, Canada, is targeting a late 2007 release. ...

Speaking of breakout stars from "The Office": You might remember Pam the secretary belting an off-key but heart-wrenching song during the recent bird funeral conducted by Steve Carell and his minions. Now, actress Jenna Fischer might be bringing her musical stylings to the big screen. "I am going to try to sing," she revealed this week while discussing her next movie, which will have her spoofing Reese Witherspoon's recent Oscar-winning role. "I'm doing this movie called 'Walk Hard' with John C. Reilly. It's a sendup of the music biopic, so it's a little bit like 'Walk the Line.' It's a fictional music biopic. He plays a Johnny Cash and I play sort of a June Carter Cash. It's very funny and very over-the-top." The flick is produced by Judd Apatow and directed by "Zero Effect" veteran Jake Kasden, who will ultimately make the decision of whether Fischer's vocals remain or get dubbed over by a trained professional. "It has yet to be seen," she sighed. "But I do get to wear a lot of pretty awesome costumes. It spans from the 1950s all the way to the present." The comedy co-stars "Saturday Night Live" veterans Tim Meadows and Kristen Wiig and should be walking the line into theaters next year. ...

"This is ... New York?" Representatives for "300" star Gerard Butler confirmed that the actor is attached to a remake of "Escape From New York," which is currently looking for financing. The original 1981 film starred Kurt Russell as the world's deadliest criminal sent to rescue the president of the United States from NYC, which has been turned into an island-wide maximum security prison. ...

There's something sinister afoot in the Magic Kingdom, argued voice actor Mario Cantone, who said Disney's latest animated feature "American Dog" has reminded him that not everything ends with "happily ever after." "It's been completely changed. There's a big upheaval about it from the Pixar folks," Cantone said, revealing the behind-the scenes squabble. Director Chris Sanders, who was nominated for an Oscar for his work on "Lilo & Stitch," essentially quit the project after "Cars" director/ new Disney animation head John Lassetter decided "American Dog" didn't meet his standards. "There's been so many different changes in the heads of animation there that it was always different, but what should have been a positive change ended up not being a good one for Chris, unfortunately," Cantone asserted. "[But] just throw the whole movie out and do another movie. Don't try to revamp what he's done, because what he did was brilliant and you're squeezing the brilliance out of it." Cantone was supposed to play a cat in the project, which originally followed an acting dog traveling throughout the American Southwest. It is unclear, Cantone said, whether his participation will be retained. "It's not official for me yet, so I don't know what's going on," the actor said. "I've been working on this film for three years, and I'm just as close to it as [Sanders]. Chris is a brilliant, brilliant man, and they should let him make his picture." One way or the other, some version of "American Dog" will come your way in 2008. ...

And I am telling you, I'm not watching it on VHS. Awards-season juggernaut "Dreamgirls" will make its DVD debut May 1 in a "Two-Disc Showstopper Edition," featuring 12 alternate and extended scenes, an image gallery with more than 1,100 frames and a never-before-seen performance of the tune "Effie, Sing My Song" by Oscar winner Jennifer Hudson. ...

Kate Mara gets to kick butt and take names with Mark Wahlberg in the upcoming action flick "Shooter," but movie karma can be a real kick in the head, the 24-year-old actress joked of "Transsiberian," a thriller set on a train through Russia co-starring Ben Kingsley and Woody Harrelson. "It's an independent film that I just finished last week, a very dark indie film which is really different for me," Mara revealed. "I worked with Sir Ben in a few scenes." But it wasn't all fun and games working with Kingsley, Mara confessed. "He was torturing me in the scenes, so I didn't actually get to talk to him very much. I just did a lot of screaming," Mara said of her character's arc. "[The torture] is foul, rough — really hard to watch."
