Scarlett Johansson has suggested that pornography can be “productive” in certain circumstances.

The actress stars opposite Joseph Gordon-Levitt in Don Jon, a film centred around a man who is addicted to porn and watches it on a regular basis.

Speaking to Marie Claire, she said: “If I found out my boyfriend watched that much porn [as Jon], I would be totally flabbergasted, for sure.

“But I think porn, like anything else, can be enjoyed. It can be productive for both men and women.”

Johansson also stars in a new Dolce & Gabbana advert alongside Matthew McConaughey, directed by Martin Scorsese.

Speaking about working with the legendary director, she said: “I had these moments where I’d be on set and I’d hear him call across the street, ‘Scarlett, can you do another one that’s a little more intimate?’

“I was like, ‘Holy s**t! It’s Martin Scorsese’.”
