Period recreation is very difficult unless you make a black and white movie.
It doesn't matter what the technology is - no one will watch a Peter Greenaway film anyway.
Film-making is a physically hard job.
I always argued against the auteur theory; films are a collaborative art form. I've had some fantastically good people help me make the movies.
The films that I do tend to polarise people's views.
Rain is also very difficult to film, particularly in Ireland because it's quite fine, so fine that the Irish don't even acknowledge that it exists.
