All humour is critical, you know? You make stupid jokes. I mean, stupidity is an infirmity, isn't it?

I love having different cultures around, but when the parent culture kind of dissipates, you're left thinking, 'Well, what's going on?'

By watching the great, old comedians I picked up a few tricks about how to do physical comedy. And whenever I could learn something, I sort of added that to my repertoire.

It's too difficult to start right from scratch and try and be funny out of the blue.

Everything in comedy's got to be exactly right, which is why making a comedic film is kind of a difficult process, because, for most of the two years of shooting it and editing it and reshooting and all of that, it's not quite right. And it's only when you just at the end, you put the final polish on it, it becomes really funny again.

I think humor is incredibly positive, I think it is life advancing. There's medical research to show that it improves your antibodies. It's all about sense and perspective.

That's a lovely experience when you make an audience laugh. Then the nerves go away for a bit. And sometimes you do things then that you've never done before that are really funny.
