If I was left to my own devices, you would see about ten T-shirts in rotation with maybe a few nice pairs of jeans - but I also like to look good. I like feeling really well put together, I just don't have the aptitude and the knowledge to do that.

I basically have the diet of a 19th-century Irish navy, apart from the litre of stout a day. It's meat and potatoes and bread and cheese: those are my four food groups.

I might like to be an actor, but there are loads of other things I'm interested in as well, like music and writing and sports. I want to keep my options open.

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.

Every day I would come to set [of Swiss Army Man] going like, "How are we going to do this?".

I could never do stand-up because it's that thing of having to get up on stage. And out of every 10 jokes you tell, nine of them have to get a really good response.

To the children who loved Harry Potter, I want to say your enthusiasm was the real magic. I so enjoyed being on the journey with you. And to the adults who bought the Harry Potter books and devoured them, I just want to say, those books were for children.
