I think it speaks to the fact that other people are as excited about originality as we are. I think the thing that has been wonderfully communicated in the trailers and all the promotion for the movie [Swiss Army Man] is that it isn't like anything else you've ever seen, and we're not just saying that. I think that excites people.

Harry Potter star Daniel Radcliffe has confessed that until recently, he thought the 16-year-old fellow tween idol [Justin Bieber] was a female. 'I only heard Justin Bieber for the first time two weeks ago. I genuinely thought it was a woman singing. I'd never heard it before. Is it big in England yet?'

I've worked every day since I was 10. I don't know how to do anything else. There is nothing else I'd rather be doing.

I've learnt a lot about certain things but you also learn through your own experience.
