“Fifty Shades of Grey” fans rejoiced when author E.L. James announced that she was adding another installment to the trilogy. However, movie fans will be disappointed to learn that Jamie Dornan (Christian Grey) and Dakota Johnson (Anastasia Steele) might not return for a fourth film.

James announced on Monday that she would publish a version of “Fifty Shades of Grey” told from Christian Grey’s point of view. The book, titled “Grey,” will be released on June 18, the character’s birthday, in paperback and e-book. The book is already topping best-seller lists with pre-orders. 

Obviously, the book will be successful, so is the studio already planning a movie adaptation? According to the Hollywood Reporter, Universal Studios owns the rights to the characters in “Grey,” so they have the necessary rights to adapt the fourth book. However, they would likely want the "Fifty Shades of Grey" lead actors to sign on.

Given that the companion book was only announced this week, it isn’t surprising that the actors aren’t committed to a movie adaptation yet. Both actors, especially Dornan, were subject to rumors earlier this year about possibly leaving the series, but fans don't need to worry. Dornan, 33, and Johnson, 25, have signed on for both “Fifty Shades” sequels, “Fifty Shades Darker” and “Fifty Shades Freed,” according to People.  

Neither Johnson nor Dornan have commented on the fourth book. There is a possibility that it won’t become a movie at all, and that might have nothing to do with the actors.

“Grey” is a re-telling of James' first novel in the series, but it's told from Christan’s perspective. That means that portion of the book, likely a significant chunk, will be scenes that were shown in the first film, but audiences will get to read Christian’s inner monologue as the same events happen. That might not work so well on screen. Filmmakers will first have to see if there is enough new and interesting material that it would warrant another movie before they make any announcements.

“Grey” will hit bookstores on June 18. Do you think there should be a movie for “Grey” or do you think watching “Fifty Shades of Grey” was enough of an introduction to Christian? Sound off in the comments section below!
