It's a product of being an actor, you know? A lot of your work doesn't end up on camera and some of the best things aren't always in the final product. But yeah, a lot of my stuff got cut and it was painful, but I know it was for the better of the movie.

Bryan Cranston has got such an incredible light touch. He comes in egoless, but with bold opinions, and he wants to play. He wants to play. And that's what I've seen in great actors all my life and what I've always tried to nurture and keep in myself is that joy of playing.

I don't know if tennis players feel like that but when you have a great opponent - although I didn't feel like he [ Ben Mendelsohn ] was an opponent - you just know your game is going to jack up and it's just going to raise the bar. I couldn't wait for that elevation.

I had to work with Ben Mendelsohn who's one of the great actors of our time. I had a lot of scenes with him and I was thrilled to be on the set with him; I just wanted to see how we were going to play it.

It's been great, I have to dig deep for really raw emotions and at the same time I have to use my intellect to say the ridiculous medical jargon while acting and treating a patient and then I have to try to have a personality and emotions as well. So it is definitely hard work.

Yes it did really. It was very exciting to find that my energy could be directed into something more useful and positive. I was starting to get panicked. I was thinking 'what am I going to do with my life?' I wasn't sure what was going to happen. Then I became crazily obsessed with acting. I suddenly had a work ethic and then everything changed completely for the better because I knew what I wanted to do with my life.

Acting is kind of a calling for me so I'm just happy to be there and do great work.
