Rachel Weisz has said it is still difficult for both male and female actors to find well-written and complex storytelling.
The Oscar winner, who is next seen in The Favorite with Olivia Colman and Emma Stone, said it's particularly unusual to find more good parts for women in one script.
She told the Press Society: "In this present-day cinema and storytelling, it is unfortunately quite unusual for me to believe, for all three characters, that all three women are so structured and layered and complex and have such different aspects of their character.
"They are not one thing, they are a million things each."
Discussing the quality of the scripts she receives, she said: "I think things are getting better.
"Films in the 40s and 50s, they always had very complex strong women who could be vulnerable and crook and royal and pleasant and all adjectives you could list.
"At the moment, it's good writing for women, but I think if a man sat here, he'd say it's hard to find good and complex writing for men, so I think human fiction might not be as interesting as that could be in the cinema.
"It's not just women, but we make up half of the world."
Weisz plays Lady Marlborough in the black comedy, opposite Colman in the role of Queen Anne, and described the Broadchurch star as "an amazing talent and one of the most beautiful people".
She added, "She's so down to earth and she's so generous and kind, she's incredibly funny, she makes me laugh so hard that sometimes I will cry with laughter in between taking.
"Just cooperate with her and be able to be opposite her in a scene and tell a story to her, it was a real honor and she is very special and incredibly easy to fall in love with like the queen, it was a movie that was in love with her queen Anne. "
The favorite is released in British theaters on January 1st.
