I think it's more important to seek the truth than to try and be perfect, to be honest.

Often you find actors have big hearts; they're quite emotional people. Talking to actors who date other actors, and talking to people who deal with other actors, they often get emotionally caught up in lots of different things. They often wear their hearts on their sleeves. They feel things quite a lot - often to the nth degree, which I can imagine could make it quite difficult to date some of us. I think it's about having an emotional availability that you can kind of draw on. But I'm also searching for that. I'll be searching for the answer to that question for the rest of my life.

More often than not, if you've got a good director and a good script you can't really go wrong.

It's better to think of life as a proper journey with a beginning and an end. Maybe, I can settle for being immortalised on screen.

I'm just trying to choose interesting, quirky projects or things with interesting directors or just movies that have a lot of people I like attached to them so I know I'm going to have a good time.

Nothing's been changed overnight. It's like watching your cat grow: you see it every day, so you don't really see it change, you wake up one day and it's a bloody great thing. Your friends come round who you haven't seen for a couple months and they're like, "Oh my god, your cat's grown so much again." And I'm like, "Has it?" But when you're living it... I just find that my life has subtly changed bit by bit, so I don't ever really notice it too much.

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.
