American teens under 17 can see 50 Shades of Grey as long as they’re accompanied by an adult thanks to its R rating—but teens living in the U.K. aren’t as lucky: The British Board of Film Classification announced that they’re giving the film an 18 rating, meaning no one under the age of 18 will be able to see the film in theaters.

The 18 rating is the equivalent of America’s NC-17 rating and is given to films with “strong portrayals of sexual activity” or “scenes of sexual violence” among other factors. According to the BBFC’s website, 50 Shades got the rating because it “contains strong sex and nudity, along with the portrayal of erotic role play based on domination, submission, and sado-masochistic practices.”

“Strong sex” seems like an accurate description: Twenty minutes of 50 Shades’ 100-minute run-time are devoted to sex, but the BBFC assures potential viewers that “all known versions of this work passed uncut”—so the sex scenes viewers (over 18, of course!) see in theaters will be the original, censor-free versions.
