I'm never going to be in something as commercially successful as 'Harry Potter' ever again. It's impossible. So that gives me incredible freedom to go off and make the slightly off-the-wall films that I want to make.

I think I'm a tiny bit like Harry 'cos I'd like to have an owl. Yeah, that's the tiny bit, actually.

I have no idea how much money I've got.

I think it was pretty obvious early on that we had both come with kind of the same attitude of "Let's just [jump] in," and neither of us was going to be precious about it. I feel like the thing that we learned is, weirdly, the most intimate thing or a very intimate thing you can do to somebody is hold their tongue with your fingers. When Paul [Dano] is making me talk [in Swiss Army Man].

I remember Paul [Dano] had said at one point that when he finished this film [Swiss Army Man] was the strongest he'd ever been just from lugging me around for [several] weeks.

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.

All these things, social media or [smart] phones or the things that distract us from each other, are fairly new. They're all fairly new inventions, and I think we're in a stage where we sort of as a whole have gotten these new toys and we're just obsessed with playing with them. I feel like after a period of adjustment it will inevitably be a regression from where we are now.
