The hottest star in this generation Zac Efron is looking to get a little "dirty" with his image in the new issue of Interview magazine, on newsstands March 24 -- and we've got a first look! "I just got to roll around in the dirt for a couple of hours," says Zac of his sandbox photo shoot. "I got pretty dirty by the end of it, so that was fun." And Zac's not getting dirty all by himself -- check out the magazine for more pix, including a provocative shot of him embracing a fully nude woman... The 21-year-old 'High School Musical' sensation is interviewed by 'Milk' director Gus Van Sant about his film roles, video games, world travel, Zen Buddhist temples and how, as he looks to the future, he'd like to perhaps get his career a little dirty too by taking some risks. "Everything I've done in the past has felt very safe," says Zac, "and it was great for awhile, but now I'm looking for a place to take chances. I want to play with things." Zac's next two movies are the age/body-switching comedy '17 Again' with Matthew Perry and 'Me and Orson Welles,' in which he plays a teen cast in the famous director's Mercury Theater troupe's take on Julius Caesar. After that, he'll take on a remake of the '80s dance flick 'Footloose.'Good luck Zac all I can say is stike the iron when it's hot.
