Actress Dakota Johnson recently quelled speculation that the film adaption of the sexy best-selling novel "Fifty Shades of Grey" won't live up to the eroticism detailed in the book.

Rumors that the movie shied away from the book's steamy sex scenes emerged last month after a select group had the chance to view an exclusive five-minute preview of the highly anticipated film at the Las Vegas CinemaCon. E! News reported that the preview was significantly toned down from the raunchy novel known as "mommy porn" and that it focused more on the romance between the two leading characters, Anastasia Steele and Christian Grey, rather than their spicy sex lives.

However, Johnson, who plays Anastasia Steele in the film, says that fans have nothing to worry about and can expect to be pleased by the movie.

"Everything is a little bit secret but I can tell you that I think people will be pleased with the movie, hopefully!" said Johnson, according to MoviePilot.com. "I'm doing this movie because I love it and I believe in the story and I believe in the books and I hope that I will do them justice."

In fact, Johnson suggested that some of the scenes are so hot and heavy that she doesn't want her famous parents, Don Johnson and Melanie Griffith, to watch the it.

"No, they won't be watching the movie—not with my permission," said the 24-year-old actress, reports EntertainmentWise.

"Anyway, I don't think the movie is something that my parents would want to see!" she added.
