What do you look for in an ideal film role?

So far I’ve been lucky enough to find parts where I have to fight to take on the project. I love that. I always get butterflies in my stomach and it feels like I fall in love. I fight to get the part and then when I finally get it, I usually freak out and I’m like, ‘Ok, now it’s up to me to do the job and it’s actually quite a challenge.’ I want to do as many different parts as possible and get as far away from whatever me is.

I’m so grateful to be where I am. You’re aware that this profession has its extreme highs and extreme lows. I’m still afraid that it’s just all going to end.
