Good actors, especially when they know their character, will come in and either tell you in advance that they have an idea, or in the middle of the rehearsal or the scene they'll let it loose and you go, 'Ah that's great.'

I wanted to get more serialized. I had this idea for an event that would click onto everybody's mortality. I said, "I want somebody to die." Fortunately for me, when I was toying with that idea, John Landgraf, who's the head of FX but also a very smart executive, came up with the idea of the ashes in the maracas. He called me up and said, "Listen, what about this, they get the ashes in a box and when they get them, they shake them and they sound like maracas." And I was like, "Okay, now I've got my throughline."

We've always talked about doing something else and Campbell Scott is always busy and I'm always busy. But when we came up with the idea of doing the potato famine as a hip hop musical, I wanted somebody who was going to bring gravity.

When I clicked into this idea of doing a band and examining a band as a dysfunctional family, I wanted to reverse that Rescue Me formula.
