I had a great time in my youth and I still feel youthful. I've no desire to look as though I'm in my 20s.
I always start with characters rather than with a plot, which many critics would say is very obvious from the lack of plot in my films - although I think they do have plots - but the plot is not of primary importance to me, the characters are.
Today's younger generation is no worse than my own. We were just as ignorant and repulsive as they are, but nobody listened to us.
