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.

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

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 did not want to be the accompanist to an operatic star. But I was at a very high level for a 16-year-old, and I maintained that. So really good, but more impressive than classically trained. So I had to take a crash course in classical technique because I really wanted to get away with playing this character [in Florence Foster Jenkins] without people saying, "That's not really accurate."

There are bits at the table read that destroy, so much so that we can't wait to do it in taping. And then, no reaction. And then there are times when I can't get the right read on a line in rehearsal, and then the audience howls at it. The strange thing is I still don't know why it happens like that. It's not like afterwards I think, 'Now I know why that worked!'

It's amazing to watch somebody who is kind of this sleazy, degenerate lothario, sex-crazed guy become sort of a romantic, settled-down man about to have a baby.

It was like in the film, when I was actually doing a take and wasn't quite sure of the context, and then in the completed film it works beautifully.In the end I didn't know why I felt so shitty doing it, and why it turns out great in the final product. I guess you have to live in that unknown.
