The 41-year-old actress, who recently called out a sexist casting call, which invited women to audition for a movie wearing cleavage-baring outfits, said she wanted to improve things for women in the film industry, reported People Magazine.
"It's just a tiny flashlight on the grossness, but there's a lot of grossness. There's stuff that has happened to me that would make your hair curl, that will go in my book someday...
"I'm interested in making the industry better so that women following in my footsteps know that they don't have to take abuse just because she wants be creative," McGowan said.
"It's brave and scary, and being brave doesn't mean you don't get scared.
"My ankles shook a little bit after I got the email firing me. I thought, 'Oh god, the blacklist, here we go.' I have so many other businesses and other interests that it doesn't really matter to me, though," McGowan said.
