Rooney Mara finds Hollywood's gender pay gap ''frustrating''.

The 30-year-old actress - whose film credits include 'The Girl with the Dragon Tattoo' and 'Pan' - has revealed she's disappointed with the industry's gender imbalance, but is also appreciative to be paid for the job she does.

Rooney said: ''I've been in films where I've found out my male co-star got paid double what I got paid, and it's just a reality of the time that we live in.

''To me, it's frustrating, but at the same time, I'm just grateful to be getting paid at all for what I do.''

Rooney also said it's important to keep a sense of perspective when thinking about the salary of a movie star.

She told the Guardian newspaper: ''It's not fair, but I think about how much teachers are getting paid, or other people who are doing jobs that are so much more important than what I do, and it's kind of hard to complain about it.''

Rooney said the way women are talked about is more problematic than what they're paid.

She reflected: ''To me, the thing that's more unfair than the pay is the terminology that's used to describe actresses who have a point of view, and want to have a voice in their life and their career, and what they choose to do.

''I've been called horrible things. If a man was acting in the same way that I was acting, it would just be considered normal. To me, that's the thing I find so frustrating is calling women spoiled brats and bitches. We just want to have a voice in our life, and I don't think that's anything that shouldn't be encouraged in any human.''
