Jamie Dornan opened up about his developing career and playing Christian Grey in the "Fifty Shades of Grey" movie this week. Dornan apparently only got the role after Charlie Hunnam backed out, which gave the "Sons of Anarchy" star something to say about the role recently as well.

Dornan first gained fame as an underwear model but struggled to break into the acting scene because he's "crap at auditions," as he said in an interview for Interview magazine's June issue.

"I know there are people who can walk into those rooms and make those lines sing on the page and get the job immediately. I wasn't one of them," he said with a laugh. "I'm still not one of them. Even after I got my first acting job, thanks to [Sofia Coppola, director of 2006's 'Marie Antoinette,' where Dornan played Count Axel Fersen], I still went a while without working."

Dornan might have better luck, however, after playing the lead in the movie adaptation of E.L. James' bestselling erotic novel. But don't worry, the 32-year-old actor won't let fame get to his head.

"I don't want to be showy," he said. "I'm not interested in seeing that, and I don't want to do it."

The role casts Dornan as an S&M-loving billionaire, but the Belfast native says there's more to Christian.

"Even Christian has two sides. Come to think of it, he has 50," he told Interview while holding in a laugh. "I guess I'm gonna be using that line all over the planet in a few months. Shouldn't waste it."

Despite the sexy role and his history of posing in his briefs, Dornan says he's not the biggest fan of his body.

"I don't like my physique. Who does? I was a skinny guy growing up, and I still feel like that same skinny kid," he explained.

Meanwhile, Hunnam, who backed out of Dornan's role a month after getting it amidst fan criticism (he blamed an alleged scheduling conflict with "Sons of Anarchy"), talked about the role that got away on Sunday.

"I felt like I had an interesting take on that character and felt like I could have done a good job of playing Christian Grey, otherwise I wouldn't have taken it on in the first place," he told Life & Style. "When you put the time into something like that and a character comes alive in your mind, it's heartbreaking not to be able to play him ... It was definitely kind of heartbreaking having to say goodbye to that character and not bring it to life."
