Scientology is not that different from other religions. And yet, at the same time, we don't have Anglicans doing the things that are alleged to be done in Scientology, at least in the Sea Org.

I sometimes get accused of being 'faux-naive,' but for me, it's really just about getting down to the basics of something.

Do I care about clothes and stuff? Not much. It's a bit sick, isn't it, people spending all that money on clothes? I'm too stingy. I wouldn't pay £100 for a shirt.

I think of myself as being quite affable, approachable, fairly easy to get to know.

'Cunnamulla' is a beautifully bleak portrait of a lonely town in which people are leading lives of sort of quiet desperation.

There have been times when I've felt inappropriately emotional. I remember making 'The Most Hated Family in America' about the Westboro Baptist Church, and being on the way to a funeral of a U.S. soldier with the Phelps family; they were going to picket the funeral.
