Sigourney Weaver: 'Women need more representation in Washington'

"We're almost 51 percent of the population, and I feel, having been a mother in New York, women get things done. We're practical," said Weaver on MSNBC's "Morning Joe."

"Our DNA has been studied and it's all about keeping the child from falling in the fire for centuries, whereas the men's DNA is all about dragging the carcass from point A back to the cave. Who would you want helping make these laws?"

Weaver, who plays a former first lady-turned-secretary of State, is taking another stab at the portrayal of the first lady, following her 1993 presidential comedy, “Dave."

"I think it's a very demanding, undervalued job, actually. You know, who knows what really goes on at the White House for the first lady?" Weaver said.

The Emmy and Academy Award nominee said she was fascinated by the take on the private and public lives of "somewhat dysfunctional" political families, but she was quick to point out that she was referring to the television show.

Greg Berlanti, the show's writer and creator, addressed the not-so-subtle similarities to the real-life story of first lady-turned-Secretary of State Hillary Clinton.

"I think a lot of the fun of a show like this is … rather than necessarily pulling from the headlines, as it were, we pulled from the narratives of people that are in politics, then it's our job to make them unique and their own character," he said.

The six-part limited series premieres on the USA Network Sunday, July 15.
