In everything I do, I like to set the idea for girls that they can do anything. I was really moved by Hillary Clinton's speech when she lost the election - she didn't want young girls to feel like it wasn't possible and wanted them to know a female president will eventually happen. That's important.

There are so many successful women working in intelligence, but it's still seen as a male-dominated world.

When I was working on 'Homeland,' there was a consultant who helped me a lot... I went to Washington and met with my consultant there, and he actually organised a lunch with several people from the Intelligence Committee.

In the past, I was always drawn to really quirky, idiosyncratic characters.
