'Rock of Ages' Star Constantine Maroulis Reluctant to See Movie Version (Video)

Adam Shankman's film version of the hit musical replaces the actor and "American Idol" alum with Diego Gonzalez Boneta.

Constantine Maroulis originated the role of aspiring singer Drew in Broadway's Rock of Ages, but he's not exactly running out to see the new film version of the hit musical.

"I can't grade it yet -- I haven't seen it yet," Maroulis told THR on the red carpet at Sunday's Tonys Awards. "I'm kinda just, like, not really ready to see it just yet. I pop up in the movie but I know it's gonna be fantastic. And the buzz is out, and so many movie stars and stuff, and I think it's a testament to all the work that I did and fans and the other cast members did all along the way."

Maroulis, who rose to stardom on American Idol's season four, received a Tony nomination for his role in Rock of Ages, which opened in 2009.

The movie adaptation, directed by Adam Shankman, replaces Maroulis with Diego Gonzalez Boneta; in a 2011 interview with The Los Angeles Times, Shankman addressed fan disappointment over the casting, explaining that he overlooked the 36-year singer because he wanted a younger star. The movie also features Julianne Hough, Alec Baldwin, Tom Cruise and Russell Brand.

Maroulis said he's got "a lot going on and I just want to see it when I see it. I'm not going to run to the premieres ... those aren't for me so much. I will see it soon, I promise."

Next up for him: the lead role in a Broadway revival of the musical Jekyll and Hyde, opening in the spring of 2013.

"I've been really lucky. I've never gone uber-famous or anything, but i've always been able to stay right there and do quality work and maintain a nice slow burn. That's all I've ever really wanted to do," he said.
