The film, which also stars Jamie Dornan as Christian Grey, is set to be the raunchiest movie picture in more than a decade, with 20 minutes of sex in its 100 minutes running time.
With that in mind, there a few people who Dornan has decided should give it a miss too.
The actor, who dated Keira Knightley from 2003 to 2005, has a one-year-old daughter with his wife Amelia Warner.
When his little girl is older, the star has admitted that he probably won't feel too comfortable with her watching him in action.
"When my daughter's 18, I'm not going to be going, 'You've gotta watch Daddy in Fifity Shades Of Grey'," he joked to the magazine. "But there will be greater things to protect her from than dad's arse on the big screen."
The British Board of Film Classification (BBFC) have unsurprisingly given director Sam Taylor-Johnson's take on EL James's "mummy porn" an R18 certificate, but said the work "passed uncut".
