Fifty Shades of Grey Movie: Hunky Jamie Dornan Will Be "Amazing," Says Costar Jennifer Ehle

Anastasia Steele's movie mom didn't read the best seller until she signed onto the film

Just how graphic will the movie version of Fifty Shades of Grey be?

We talked to Jennifer Ehle, who will play Anastasia Steele's mother in the film, about the film's possibly NSFW moments when we caught up with her on Saturday at the BAFTA Los Angeles Jaguar Britannia Awards.

The Zero Dark Thirty actress admitted she wasn't sure how NSFW the movie will be. "Being a visual medium, it's hard to tell from a script what something's going to be like," Ehle said.

Ehle didn't read E.L. James' erotica best-seller until after she signed on for the big screen adaptation. "It's extraordinary," the two-time Tony winner saud. "I'm excited. I feel kind of like a tourist…I'm along for the ride, as it were."

Cameras are reportedly going to start rolling on Dec. 2, about a month later than the original plan. The delay came after Sons of Anarchy star Charlie Hunnam unexpectedly dropped out of playing Christian Grey and hunky actor Jamie Dornan was announced as his replacement.

"I didn't follow any of the drama, but I think Jamie will be amazing," Ehle said.

Fifty Shades is set to hit theaters on Aug. 1, 2014.

The film also stars Dakota Johnson as Anastasia, True Blood hottie Luke Grimes and The Lords of Dogtown actor Victor Rasuk. (Both Universal Pictures and E! Online are part of the NBCUniversal family.)
