With the lead cast members for Fifty Shades of Grey now in place, fans are beginning to speculate just how erotic the film will get, especially the ladies, who are surely curious about how Sons of Anarchy standout Charlie Hunnam will clean up in order to get down and dirty in the Red Room of Pain as Christian Grey.

Although she's yet to meet the future cinematic version of Grey, actress Jessica Chastian will be co-starring with the English actor in Guillermo Del Toro's upcoming horror flick, Crimson Peak.

While promoting her current movie, The Disappearance of Eleanor Rigby, the 36-year-old gave E! Online her take on what the movie adaptation of E.L. James' racy read is about.

"I heard it's like steamy sex," she said.

The entertainment site's reporter, Marc Malkin, further elaborated on the substance of the film, telling her, "It's really kinky. It's like porn," he said.

Having no qualms about a little naughtiness, Chastain gave the following response:

"That's fine. I like written porn. The imagination is very strong," she clarified.

Fifty Shades screenwriter Kelly Marcel stated that she'd be adhering to the original content of author James' books with lots of sex and raunchiness. The highly anticipated flick is scheduled to launch in theaters on Thursday, Aug. 1, 2014.
