I think, as an actor, and particularly if you are playing the lead in something, you have to view yourself as the head of department for the cast. All of the other departments are accountable and have somebody at the helm who is leading them all the time, and I don't think that the actors should be any different.

It's interesting for myself, growing up as an Asian-American filmmaker. Coming into the industry, my parents always said, "No one's going to give you the opportunity. You just have to do the work. Be better than everyone else, so they can't deny it."

I think I tried to steal a Mars bar once from a shop but then I went and put it back.

We sing a lot of the soundtrack in this film [Swiss Army Man] - me and Paul Dano - and on the last day of filming we had to just get into the back of our sound mixer's van and record a really crappy, rough version of the singing then. For some reason that was one of the most fun days.

Working hard is important. But there is something that matters even more, believing in yourself.

I grew up listening to show tunes in the back of the car.

The best thing I've learned is, if you're going out, never go out alone - you leave yourself vulnerable. If you've got someone else there you trust, they can say, be wary of that person. I probably used to be too trusting of people.
