I love the challenge of playing characters forced on life-changing emotional journeys. To work on a project with Billy Crudup and Sam Rockwell is just a dream come true.

Obviously, you never shoot the scenes of a film in order or only very rarely.

I'm quite severely dyslexic so I struggle with acting in certain ways. I always have to put in triple the amount of effort, which would always frustrate me a lot. I suppose that some people can just look at a script once and know it. That's not me. I really have to spend a bit of time with the lines. But it's my job and I've got better and better at it. If you're learning a lot, things start going quicker. Doing the lines with repetition and you just get it in your head somehow.

Have you seen Cowspiracy? It takes a lot more land to feed a meat eater than to feed a vegan or a vegetarian. It's something I'd love to get into but it's very hard to persuade people to stop things they've been doing for a long time. So maybe it needs to start with the next generation. Everyone needs to raise their children with a bit more responsibility.

I would be the last person on earth to complain about what I do - I feel very fortunate and I know there are a million jobs in the world that are much, much harder - but it's not always an easy or glamorous thing to do, that's for sure.

I like to cook Vietnamese pho or vegetarian curries. I need to cook more but I need somebody to cook with.
