Shonda Rhimes wants to bring an end to the phrase "smart strong woman" when it comes to roles on the big or small screen.
The writer and producer - who has been a driving force behind the likes of 'How to Get Away with Murder' and 'Scandal' - has urged everyone to focus on character complexities rather than limiting actresses to such defined parts.
She tweeted: "Okay. Entertainment industry, time to stop using the phrases "Smart Strong Women" and "Strong Female Leads".
"There are no Dumb Weak Women. A smart strong woman is just a WOMAN. Also? "Women" are not a TV trend -- we're half the planet. (sic)"
The 'Grey's Anatomy' creator is no stranger to developing interesting characters for women on television, and she has spoken out about the issue in the past.
In an interview last year, Rhimes admitted she hates being asked how she writes "such strong" parts, because she doesn't necessarily see anything remarkable about them showing such qualities.
She said: "Every time somebody says, 'How do you write such strong, smart women?' I find it appalling, because it suggests that there are stupid, weak women and that's who is generally out there...
"Mostly I just wanted to write people I wanted to watch. I remember being very surprised to discover that people thought that Meredith Grey and Christina Yang were revolutionary. Because I felt like they were just women I knew."
Previously, Shonda has also used her Twitter account to share inspiring posts for other women.
Last month, she tweeted artwork that read:
"There is no force more powerful than a woman determined to rise."
