We all have those dreams of going back in time and seeing what it was like when our parents were younger. Maybe we don't all have that dream. I don't know. Getting to role play or step back to a different moment in time and see things through a different lens is something that resonated with me, for sure. We don't get to do that, generally, but when the right neurological disorder lines up with the right unstable woman, that moment presents itself. Getting to know where we come from is a really profound way of getting to look at who we are.

I always honestly dreamed of coming to Second City in Chicago, although I've never even been there to see a show. But I did a ton of sketch comedy at the Second City in LA, which (at the time, in a different location) wasn't really a theater, it was just a space where you took some classes.

I wanted to move on. I wanted to do acting. The next thing I did after [MADtv] was a good hybrid of that. I did this show with Bob Odenkirk and Derek Waters (creator of Comedy Central's "Drunk History") and it was a little homegrown thing that we shot and then we sold it to HBO. We made a pilot and HBO didn't pick it up, but then we made all these webisodes. This was before streaming stuff online made any sense. (The episodes are available on YouTube). Nobody even knew how to watch things on the internet.

That is what's disconcerting about working on the show, you can't seem to get an instinct about what works and what doesn't. It happens a lot, and in different ways.

I had to learn all the pieces backward and forward [to play it in "Florence Foster Jenkins"]. We practiced on weekends. It was very much like being in school, except it was with Meryl Streep. Like, I would go to her apartment and we would practice Mozart's "Queen of the Night."

What I wanted to do was music, until I was about 16. But it was jazz and rock, never classical music.

There are those moments where you realize that your parents or your heroes are human and are fallible. That concept, in and of itself, is something that is dangerous to me, in a good way. It's exciting and scary to meet those people.
