When Fifty Shades of Grey hit bookshelves back in 2011, E.L James' novel well and truly took the world by storm.
After the first book sold 125 million copies worldwide, even beating the untouchable Harry Potter series in sales, developing the erotic trilogy into movies became an inevitability.
But despite all of the success, Sam Taylor-Johnson, the director of the first movie, said she wishes she'd never even been a part of the project.
Speaking to The Sunday Times, Taylor-Johnson revealed, "With the benefit of hindsight, would I go through Fifty Shades of Grey again? Of course I wouldn't. I'd be mad".
Considering how successful James' books had already been, the author was given a huge, unprecedented amount of creative control over the movies - something the director struggled with.
