The different variables involved in anything creative, really, are massive. When it comes together, it just clicks, I suppose.

Tone is always such an important thing, and that's achieved through a multitude of people. It comes through the writing, it comes through the way it's shot, and it comes through the production design and the sound design.

I love playing a character that has more than 90 minutes, and that keeps going.

I think it's amazing to have one writer write every episode of a series. It's very rare, I think. You get a voice that continues.

There's comedy in tragedy, and tragedy in comedy. There's always light and dark in most jobs. Whether it's framed as a comedy, drama or tragedy, you try to mix it up within that. You can work on a comedy and it's not laugh-a-minute off set. You can work on a tragedy that's absolutely hilarious.

It's a real testament to the amount of skill and talent involved, across the board, whether it's the production design, the construction, the costume design, the other actors, the way it's shot, the directors we had on it, or obviously John's writing. When things do go well, it sometimes seems easy, in a weird way, but it's actually down to a lot of cogs working in a big machine. But, I'm certainly happy to be going back. I'm excited to carry on.
