Jamie Dornan is already starting to become a household name, and his upcoming movie, Fifty Shades of Grey, hasn't even hit theaters yet. It is still up in the air, however, if the fickle mind of Hollywood will allow the actor to ride the fame wave for a long time.

Dornan recently appeared on BBC's The Graham Norton Show where he admitted that "I have no idea" when it comes to how playing Christian Grey in the movie adaptation of E.L. James' erotic novel will change his life.

"I mean, look, we're in a really powerful position that 90-plus million people have read the book so if like a third-I mean, a hundredth of those people-that's successful if they go see the film," Dornan said.

Success comes and goes, however, and the 32-year-old actor does not know what is next.

"It's a nice position to be in, but I have no idea what it's gonna do," Dornan continued.

Dornan gained fame in the United States playing Sheriff Graham in ABC's Once Upon a Time in 2011. Dakota Johnson, who can also be considered a newcomer, joins Dornan in the lead as Anastasia Steele. Recently, Kristen Chenoweth, the girlfriend of Fifty Shades of Grey producer Dana Brunetti, shared her opinion on the film's stars.

"I think that Dakota and Jamie, I met them both -- I didn't see their work because it's a closed set, but I do see how they both got the parts -- could not have been lovelier," she told E! News. "That always helps.'You're talented and you're nice?' Fantastic!"

So does all this positivity mean that the Fifty Shades of Grey movie and Dornan will have a sequel?

"I have no idea," Brunetti told MTV. "I have no idea yet. We haven't even started discussing that yet. We just want to get this one wrapped and get it cut. We'll see the cut, see how it goes, and once it's released, we'll start discussing what happens next."

Fifty Shades of Grey hits theaters Feb. 13 2015. The trailer is expected to be released soon as the movie is done filming.
