Daniel Radcliffe "naively thought" gender equality wasn't an issue in Hollywood anymore.
The Harry Potter star admits he finds it "nuts" that there is still such a big pay gap between men and women in the film industry and thinks it is about time Hollywood "steps up" on the matter.
He said: "It is nuts to me. I'm incredibly glad gender equality has come up because I had just f***ing naively thought this was not an issue any more because how can this still be happening?
"It's crazy. It is definitely the time for our industry to step up. Especially if we want to pride ourselves on being a liberal, progressive industry then you can't be doing that."
The 26-year-old actor also was shocked to find out about the pay gap between the male and female stars in 'American Hustle'.
