Lena Dunham

The 'Girls' star has been a feminist since she was a child and explained how the mindset was installed by her mother.

She said: "I grew up with a mother who had come of age in the '70s and feminism was a huge part of her formative identity, and so for as long as I can remember words holding power in our household, that was one of the most powerful ones.

"I think that she instilled it in me so deeply and I sort of thought, 'OK, she did the job and now the job is done and I just get to call myself a feminist and revel in what my mom did.' And until I came to Hollywood and started witnessing the subtle but totally systemic sexism that pervades our industry, that's when I really turned my attention to it again in a powerful way and it became a huge part of my adult identity and not just my inherited identity."
