However, she said that there are some good projects being made. "But there's a feeling that there are more (good roles for women) and there are people being very proactive, like Emerald, like Phoebe Waller-Bridge, like Margot Robbie. Women who are being very deliberate about creating new and exciting things," she said.

Mulligan has played a lot of ‘mom roles', and she says she was apprehensive about playing someone without kids in "Promising Young Woman".

"I'd been exclusively playing mums for a bit. I had a teenage son in Wildlife and then I had children in 'Mudbound'. And I had been performing this Dennis Kelly monologue ('Girls and Boys') in which I had two children," she told The Guardian newspaper.

She added: "Then, suddenly, I was a bit like: 'Can you still buy me as pre-kids?' It wasn't anything I'd massively articulated, but I was like, 'OK, I'm gonna be in that zone again.' There were lots of things about it that I felt like, 'I have no idea how to do this.'."
