Writer Kelly Marcel will never watch 'Fifty Shades of Grey' because the changes author E.L James made to her script left her heartbroken.
Marcel has confessed she refused to see the film - which was based on James' novel of the same name - after the pair clashed while penning the script.
Kelly insists seeing the film - which was released in February and stars Dakota Johnson and Jamie Dornan - would be too painful as it is "much different" to the one she had originally imagined.
She explained: "My heart really was broken by that process, I really mean it. I don't see it out of any kind of bitterness or anger or anything like that. I just don't feel like I can watch it without feeling some pain about how different it is to what I initially wrote."
Marcel also opened up about the strained relationship between James and director Sam Taylor-Johnson, who has dropped out of the next installment of the racy franchise.
She told Vulture: "There was a moment where we were weeks away from shooting ... and it was clear that that was gonna be a struggle.
"It's very difficult to come on as a director and to be handcuffed that way and not be able to fulfil your creative vision because there are certain restrictions on you. But at the same time, I would argue that it was very clear that that was the way it was going to be.
"She would always let me argue and fight for things that I felt passionate about. In the end, I think we ended up with a draft that was a halfway compromise, but she had still been very brave about what she had let go. Ultimately, Erika did have all of the control."
