When I was a kid I wanted to be serious like Daniel Day-Lewis. No one really dreams of being a comic actor do they? Now I realise how stupid that is - and it's because comic acting isn't taken seriously enough. It's a discipline. You know instantly - either you're funny and getting the laughs or you're not.

The follow your dreams thing is really important because so many people are railroaded into taking other paths by their family their friends people who should be supportive going 'What are you talking about?' Even just seemingly regular career paths but if it's not what people expect for you they kind of react funny.

It's funny now how much we look at - whatever you want to call it: art design culture stuff film - online and how in the online world you're instantly global.

I have an all-Japanese design team and none of them speak English. So it's often funny and surprising how my ideas end up lost in translation.

Design is a funny word. Some people think design means how it looks. But of course if you dig deeper it's really how it works.

It's funny though speaking of fathers and sons because me and John Goodman played father and son like five or six years ago in the film 'Death Sentence ' and I got back with him again in 'Inside Llewyn Davis.'

And in a funny way each death is different and you mourn each death differently and each death brings back the death you mourned earlier and you get into a bit of a pile-up.

For a culture that has such a problem with death we seem to deal with it in a quite bizarre way. We see people shot killed and blown up and we find it funny and sexy and all those things. But the reality of it is that every day people die and people are really sad and they grieve and they go through a really difficult process with it.

I made a supreme effort not to do that thing that parents do which is to bore people without children to death by going on and on about how funny their children are so there's none of that hopefully.

I don't really talk about my personal life. It's a strange and funny and weird thing. Sometimes you have a conversation with someone and the paparazzi snaps a picture of you and people decide you're dating. If I try to answer everything people say I would be up all night.
