London in the '70s was a pretty catastrophic dump I can tell you. We had every kind of industrial trouble we had severe energy problems we were under constant terrorist attack from Irish terrorist groups who started a bombing campaign in English cities politics were fantastically polarized between left and right.
On 'Into The Wild' I spent months risking my life and on 'Speed Racer' I spent 60 days acting in front of a green screen. No danger to my physical self but I sure had to use my imagination.
