"Fifty Shades of Grey" author E.L. James has confirmed that his fourth book titled "Grey" is already written. Fans are obviously excited about this and wondered if the fourth installment will be turned into a movie as well.

In a published report, actor Jamie Dornan talked about filming the second and third movie back to back. He said that he believes it was better for everyone that they did it that way since it kept them motivated and it was easier for them to be in character.

"I move on very fast in my mind. As much as from the outside people think you are synonymous with one character, but I'm very much like, 'Right, that's done', and move on to the next project and worry about that character," Jamie Dornan said.

"I think as an actor, you do just want to mix it up," he further explained. "You don't want to be typecast."

So there it is, the 34-year-old actor Jamie Dornan will not return as Christian Grey should a fourth movie be made.

The actor also talked about his feud with "Fifty Shades" author E.L. James and movie director Sam Taylor-Johnson. He said, "Not just Sam and Erika, everyone is feeling the pressure. Everyone is trying to complete their role as best they can. For Erika these are her babies, these mean more than her to anyone else."

The movie "Fifty Shades of Grey" based on the 2012 bestselling book has grossed $571 million worldwide and was considered as a box office hit. The sequel "Fifty Shades Darker" will be released on February 10, 2017, while the third installment titled "Fifty Shades Free" will hit the theaters on Feb 09, 2018.

For now, fans can just feast their eyes on Christian Grey and Anastasia Steele's steamy scenes in the new trailer for "Fifty Shades Darker."
