'Fifty Shades of Grey' Movie: Dakota Johnson Overdoing Diet for Film Role?

Things might have gotten a bit overboard for "Fifty Shades of Grey" film star, Dakota Johnson. The actress who plays Anastasia Steele is allegedly overdoing her diet for her sexy role. Sources claim the she has taken the juice diet quite seriously which might not be too healthy for her.

Dakota Johnson is getting all worked up for the film adaptation of E.L. James erotica novel. While Dornan is working out his assets for a full frontal, Johnson is trying to keep a great figure with the help of a juice diet.

"They are sometimes starting as early as 6:30 a.m., and there are long hours," reveals a source to E! News, adding, "The juices help them feel great and maintain a high nutritional intake. They energize you and you don't get the same crash with sugar or coffee. It is a more sustainable energy level."

However, sources claim that aside from the special diet, she's been starving herself to keep in shape. Yet, that might not be the case given Dakota is aiming to be healthy. Aside from the juice diet, the actress has been spotted leaving a fitness gym in Vancouver.

Well, it seems that all is going well for the film. Earlier this week, another star was cast into the film set to play Anastasia Steele's stepfather. As for Dornan and Johnson, a number of photos from their shoot have been made available online.

A few photos are that of the couple's first kiss. Check it out here. Another photo is that of Dakota holding a very familiar brown envelope. See the photo here. Could the envelope be the contract for BDSM between her and Christian Grey?

This would only mean that soon enough fans will get to see behind-the-scenes photos of the couple in the Red Room of Pain. Production executives claim two versions of the film would be released namely Rated R and NC-17.

For those who have only heard of "Fifty Shades of Grey" now, the film follows the story of Anastasia Steele caught in an S&M romance with her boss, Christian Grey. The film has been adapted from E.L. James best-selling novel inspired by "Twilight."
