I didn't know this about myself but when 'Pirates of the Caribbean' came out I realised that I didn't enjoy a huge amount of recognition. I didn't react to it well but I think life is about finding out who you are and what you like. So I started doing independent movies and art-house films instead.
There are signs that the age of petroleum has passed its zenith. Adjusted for inflation a barrel of crude oil now sells for three times its long-run average. The large western oil companies which cartellised the industry for much of the 20th century are now selling more oil than they find and are thus in the throes of liquidation.
