'Fifty Shades of Grey' features 20 minutes of sex scenes, according to reports, a fifth of its total 100 minute running time.
That figure makes it the mainstream film with the most sex to have been released in the past 10 years.
The adaptation of E.L. James erotic best-seller contains 12 sex scenes in all, according to information obtained by the website Mr Skin, which collates data from adult and erotic movies.
Starring Jamie Dornan and Dakota Johnson as Christian Grey and his lover Anastasia Steele, the Sam Taylor-Wood-directed movie is due out on February 13.
However, despite the volume of sex in the movie, its stars and its director have been at pains to play down the risqué nature of the movie, Dornan even saying he doesn’t believe it is pornographic or even erotic.
“I just wouldn’t use the word ‘erotic’ - it brings up different ideas for me. I just think we tried to make a good picture, you know?” he told the Sunday Times.
Asked whether he will live up to the fantasies of the book’s fans – it’s sold over 100 million copies worldwide – he added: “Nobody can walk in and embody what she wants. It doesn’t exist.
“But I hope I’m the closest thing. I hope I’m a good enough actor, and it’s passable.”
Taylor-Johnson, who is married to 24-year-old Aaron Taylor-Johnson said to The Guardian: “I didn’t want it to be graphically explicit, and I know that’s going to be disappointing to some people.
“It’s the build up and titillation of touch and sensuality. So I don’t think it goes into the realm of porn.”
In another interview, she added: “The thing that was most difficult was how and where to pepper the sex, and to not make it feel like it was gratuitous.
“So it had to be a really strong part of the story, and I had to give characterisation to each sex scene, to make them different.”
The movie is among the hottest anticipated of the year, with studio Universal claiming the trailer has been watched online 250 million times.
