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.

Weirdly, some of the middle stuff of the descent into something going wrong were the hardest, tonally. You don't want to jump the gun and be instantly paranoid about the fact that she has made coffee wrong because that would be weird. It's the slow build and letting it sink in. If they say everything is okay, you believe your partner. You don't want to rattle the boat too much on your honeymoon.

The story revolved around this universal identifiable fear that we must all have, at some point, when you commit yourself to being with another person, to have and to hold until death do us part. It's a huge thing. I just felt like it was a brilliant examination of what would happen, if the person that you trusted implicitly and thought you knew every follicle and pour of, inside and out, started to not be that person anymore, inside. Physically, they're still there, but they're not there mentally.

I look for something that grabs me and that's heartfelt, and that's coming from a good place. I want to work with good actors and with directors that I can learn from.

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

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.

Personally, I just want to work on stuff that challenges me, that excites me, and that I think is original. You want to do something that does to other people what films do to you. It's the most wonderful thing in the world when you can lose yourself from reality and go into a story, and believe it and go on that journey with people, and you have to work that will somehow do that. It won't always, but hopefully sometimes.
