Sucker Punch follows a young girl (Emily Browning) who is institutionalized by her wicked stepfather. Retreating to an alternative reality as a coping strategy, she envisions a plan which will help her escape from the facility.

Jena Malone and Jamie Chung also star.

Thanks to for the video.

Vanessa Hudgens’ upcoming film roles are definite departures from her squeaky-clean work in “High School Musical” — particularly in the upcoming action-thriller “Sucker Punch,” directed by “300″ helmer Zack Snyder.

When MTV News recently caught up with the young star, at Neutrogena’s Wave for Change with Global Giving, she revealed just how different the role really is. Hint: She’s traded singing for slinging bullets.

Although the film will present at Comic-Con this weekend, Hudgens said it is far from completion. “It’s probably, definitely not done,” she said. “There’s so much CGI in it, it’s ridiculous.”

Regarding the film joining in on the popular 3-D trend, Hudgens was enthusiastic about “Sucker Punch” going that route. “It would be so badass,” she said. “It’s already really badass, but having it in 3-D … having my tomahawk fly towards your face, [it would be] just too cool, you know?”

Speaking of badass, Hudgens continued to cite the gun-slinging as her favorite aspect of filming.

“Shooting a .50-cal [machine gun], there’s nothing like it,” she said with a smile. Hudgens added that she and her female castmates (including Jena Malone, Abbie Cornish and Emily Browning) found a new sense of empowerment with their gun-wielding skills. “I think all of us girls loved it so much. We’re all strong individuals, and when you give us a gun … you kind of unleash something.”

Hudgens is also excited for fans to see a sneak peek of footage, which will premiere at Comic-Con in San Diego. “I’m going for the first time, and I’m so excited!” she exclaimed. “I want to go dress up in a mask or paint my face so I can walk around in the crowd.”

Most of all, Hudgens can’t wait to see the first clip from the film, which is slated to premiere Saturday. “I’m really excited [for fans to see it]. There’s this beast that’s been unleashed with all of this. … I’m a lot tougher, stronger, badass — I don’t want to sound cocky, but it’s cool.”

At the premiere of his new movie Charlie St. Cloud last night, V swore she wasn’t bothered by his spit swapping scenes.

“I took myself out of it and just watched it like anyone else would,” Vanessa told E! News nonchalantly.

She’s more concerned with where her famous boyfriend will be sitting when she makes her debut as Mimi in Rent at the Hollywood Bowl…

“Wherever they put him! I don’t wanna know where they put him. I’ll be distracted!”

As for Zac, he tells E! News that having his girlfriend at the premiere helps him relax. “She’s just calming my nerves and saying she’s so proud,” he confessed. “It really means a lot to me!”

And no matter where he sits for Vanessa’s musical theater debut, there’s no doubt he’ll be in the house. “I wouldn’t miss that for the world!” he told us.

Vanessa Hudgens attended the premiere of Zac Efron‘s new movie Charlie St. Cloud last night, July 20, in Westwood, CA. Vanessa looked incredibly stunning in her Reem Acra dress, Jimmy Choo shoes, and Ferragamo bag. I have added 37 HQpictures to the gallery of Vanessa at the premiere, including some very cute Zanessa pictures!

Also, here are some videos. The first includes interview with both Zac and Vanessa for Entertainment Tonight and the second is a video of the paparazzi taking pictures of Zanessa on the red carpet. The beginning part of the second video is all Zac, then Vanessa comes in at about 1:05 and then from 3:40 on is all Zanessa together:
