She doesn't just play a tough chick on "Agent Carter": Hayley Atwell is one in real life.

Atwell participated in a "Women Who Kick *ss" panel this past weekend as part of San Diego Comic Con and spoke out about sexism.

Along with Gal Gadot, who plays Wonder Woman in the upcoming "Batman v. Superman" film, and "American Horror Story" star Kathy Bates, Atwell answered questions on experiencing sexism on set.

The actress was asked a question about having to change her characters lines because they were sexist, reports E! Online, but Atwell went on to explain how she takes that one step further.

"It's not so much things she wouldn't say," Hayley said. "It often involves me just going, 'I don't think she would be naked in this scene. There's no need for that. I'm not doing it just to fulfill your weird little fantasy.'"

The actress has spoken out about sexism in the media before. Early this year, she told HitFix what she thinks is the problem with sexism today versus sexism in the 1940s, the period "Agent Carter" is set in.

"I think it's much harder these days to identify moments of sexism," she said. "Because they just have very sophisticated ways of hiding themselves."

With so many Hollywood stars making careers by objectifying themselves and others struggling to understand efforts like feminism, Atwell has a point.

"I think prejudice is always going be there," she said.

"We just have to trump it. We just have to keep on exposing it and trumping it and revealing it and naming it and making it clear and bringing it out into the light, out into the open to see it for what it really is. And then it really, truly has no power."

Atwell also recently made fun of herself while bringing up the issue of photoshop on Twitter. After a fan posted an image of Atwell and asked her why was she so beautiful, the actress responded with simple but effective "Why am I so photoshopped?"
