'Insane Farting Corpse' is a really hard movie to do a Q&A for. The audience is still kind of reeling and being like, "I don't know what to ask."

My favorite phrase, that a friend of mine who worked on the Potter films and was a lot older than me would use in front of me, and I picked up from him many great phrases - the English have a lot of great idioms for sweating. I don't know why that is. But that's what we do. I feel like it's particularly our country; probably everywhere has a lot of idioms for sweating. He always said, "I'm sweating like a glassblower's asshole," which I always found an incredibly strange and yet vivid image.

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.

Obviously, I've been very lucky in general in my career, but I feel that I've been very lucky in terms of having directors come along at the right times who have taken me to the next level of where I needed to be.

I'm an atheist, but I'm very relaxed about it. I don't preach my atheism, but I have a huge amount of respect for people like Richard Dawkins who do.

How irritating it must be for people, to be bombarded with me!

I'm a serial monogamist. I'm not one of those people that can date loads of people at the same time, it's all too complicated.
