The actress revealed how complicated it was to shoot the movie, which
    underwent several changes during filming
The 'Fifty Shades' saga,
    based on the novels by E.L. James, left its mark on the world of film.
First
    released in 2015, the movie tells the story of passionate relationship
    between a recently graduated virgin girl and a young tycoon. Love, drama and
    eroticism are at the heart of the story.
Now, four years since
    the last release of the series, Dakota Johnson, who stars as Anastasia
    Steele, has revealed just how complicated it was to film the movie.
  
Johnson, who's latest film 'Cha Cha Real Smooth' was recently
    released on Apple TV, spoke to Vanity Fair about the experience.
"I
    was young. I was 23. So it was scary," she said. "It just became something
    crazy. There were a lot of different disagreements.
"I haven't
    been able to talk about this truthfully ever, because you want to promote a
    movie the right way, and I'm proud of what we made ultimately and everything
    turns out the way it's supposed to, but it was tricky."
  
According to Johnson, who was catapulted into fame thanks to
    the film, E.L. James was one of the main problems while shooting.
"She
    had a lot of creative control, all day, every day, and she just demanded
    that certain things happen," said Johnson.
"There were parts of
    the books that just wouldn't work in a movie, like the inner monologue,
    which was at times incredibly cheesy. It wouldn't work to say out loud. It
    was always a battle.
"We'd do the takes of the movie that Erika
    wanted to make, and then we would do the takes of the movie that we wanted
    to make.
  
"The night before, I would rewrite scenes with the old dialogue
    so I could add a line here and there. It was like mayhem all the time."
Despite
    the chaotic environment, Johnson says she has no regrets.
"No. I
    don't think it's a matter of regret," said Johnson.
"If I had
    known at the time that's what it was going to be like, I don't think anyone
    would've done it. It would've been like, 'Oh, this is psychotic.' But no, I
    don't regret it."
