Dakota Johnson says making 'Fifty Shades of Grey' was like 'Harry Potter'.
The 25-year-old actress - who portrays Anastasia Steele opposite Jamie Dornan as Christian Grey in the raunchy film - admits the movie has a "wild" subject matter but insists being on set was much more family-friendly.
She said: "It is really wild. When we were filming the movie it didn't feel that way on set. It was this weird other world environment, like 'Harry Potter'. "
Dakota is the daughter of Hollywood stars Melanie Griffith and Don Johnson but she insists her upbringing was nothing out of the ordinary.
She told talk show host Jimmy Fallon: "I mean, they were just normal parents to me."
Elsewhere on the show, the actress and the host played a game called 'Anything Can Be Sexy', where they read a series of random sentences in their most sultry voices.
Jimmy's first attempt fell flat, with him saying: "I want to go fishing this afternoon, do you know where I can buy grubs or worms."
Dakota fared better as she gazed into the camera and said: "Excuse me while I go slip into an old pair of sweat pants."
