I found out that detectives are really good dressers. I'm not even exaggerating. The woman I interviewed had these fantastic fuschia suede heels on that I coveted. And that they're invested in their jobs the same way you and I might be. We think of them as doing these jobs that we could never imagine doing, but their relationship to what they do is the same as our relationship to what we do.

One of the things the police officers told us in the first minutes of being with them is that the way that they cope with their job is by using a lot of inappropriate humour. It's really a lovely opportunity to try to challenge our ideas of what it is to deal with complex issues, and that they're not always dower. Having that kind of humour along with the pathos for what people are going through is a really nice challenge.

I'm a character actor; that's my skill set.

You have to carry so many archetypes as an actor, especially as a blonde-haired, blue-eyed one.

I injured myself quite badly when I was seventeen. I broke my ankle, and it didn't heal in such a way that I could keep dancing at the level I wanted to. It wasn't like, 'Oh my god, I'll never play the violin again.' I could, but not at the level I wanted. So, I segued into acting, the other thing that was also meaningful to me.

I'm really lucky. I never really felt like LA was the Mecca, that you "made it" if you made it somewhere else. I've been a journeyman actor for my whole career. I just sort of went where I was invited. I worked the early part of my career in Canada before I had the luxury of doing an American series, which brought me down to LA.

The sneak-peeks you get off the top are of them in their real life. You're more invested, you know both of them, and you've already made assumptions. A murder who would murders someone - that makes them immediately bad - but here you see them in a different.
