Is Nicolas Cage trying to be Elvis? Some might think so. The star of “Captain Corelli’s Mandolin” sang like Elvis in the film “Wild at Heart,” dressed like Elvis in “Leaving Las Vegas,” and is currently dating Elvis’s daughter, Lisa Marie Presley. And while he’s definitely not the king, he could be feeling like one. That’s because he’s at an all-time high in his career, having just cemented his hand and footprints in the forecourt of Graumann’s Chinese Theatre in Hollywood and carrying an anticipated summer blockbuster. “I’ve never been in these sort of large-scope, epic dramatic films and I thought it was time to try to do that,” he told “Good Morning America” Friday. And although Cage, 37, is a veteran of over 40 films, including “Moonstruck” and “Raising Arizona,” he said he’s still got a lot to learn. “I see myself very much as a student of acting still,” he said. “And I think if I take roles like Captain Corelli, where I have to speak in an Italian accent and learn how to play a mandolin and march like an Italian soldier — there’s a lot that could go wrong. But maybe, maybe something will go right, and I’ll learn.”
