“Fifty Shades of Grey” just opened over Valentine’s Day weekend, but eager fans already are clamoring for “Fifty Shades Darker,” the sequel to E.L. James’ best-selling erotic novel. It was originally reported that Sam Taylor-Johnson would return to direct the second movie of the trilogy, but the Sun is reporting differently.

Even though the British director said she “signed on” for another movie, she does not want to continue with the trilogy since she and James fought constantly on the set of “Fifty Shades of Grey,” the Sun reported via the U.K.’s Daily Mail.

“Sam won't be back for the 'Fifty Shades' sequels. She wants out and Universal knows that's the right decision,” film insider Dan Wootton told the newspaper Tuesday. “Her relationship with Erika has become absolutely toxic -- they despise each other and blame each other for the problems with the film.”

James, whose first name is Erika, wanted more sex scenes and Johnson wanted to lead with illusion, according to the report. The director was quick to admit the two women “clashed” about how the film should be made.

“We definitely fought, but they were creative fights and we would resolve them," Johnson said while discussing what it was like to work with James in an interview with Porter magazine. "We would have proper on-set barneys, and I'm not confrontational, but it was about finding a way between the two of us, satisfying her vision of what she'd written as well as my need to visualize this person on screen, but, you know, we got there,” the director said. "It was difficult, I'm not going to lie.”

Still, Johnson wanted to be a part of the film. "I knew how it should be made, needed to be made, and I felt a certain responsibility to make it the right way," Taylor-Johnson said about the sadomasochism-themed movie via Us Weekly. "I felt it was an incredible story. It's like a dark twisted fairy tale, very romantic, and it was interesting how troubling it was, and how romance and the darkness interweaved."

On Twitter, James has been busy promoting “FSOG,” which grossed $248.7 million at the global box office in its opening week.

Taylor-Johnson has not made a public comment about not being involved in “Fifty Shades Darker.”
