I always watched a lot of TV. As a kid, I’d gorge on Diff’rent Strokes and The Facts of Life. When I was 12, I was offered a part on One Life to Live and turned it down. I was nervous about developing bad acting habits as a child. Even at 13, when I did the pilot for My So-Called Life, I knew it was unusually excellent material. It’s so rare to be on an immediate and exact parallel with the character you’re playing. It was a relief to blast all of my teenage grievances out into the world. When Homeland came around, I was scared. My character, Carrie Mathison, is very troubled. To play somebody wrestling with a bipolar condition in very high-stakes circumstances seemed rather fatiguing. But, ultimately, it was too good to ignore. It’s that classic thing: If it scares you, you don’t really have a choice.
