When I make decisions based on other circumstances, things don't necessarily go so well. So sometimes, even if something seems commercially tempting, I've learned that if it's not what's in your heart, it's probably not what you should do.

I became a real Shell Motor Oil expert, and I did this 25-minute film. It turned out really well and, as a result, they offered me more work and lots of commercials to direct.

When I follow my heart, usually the results are good.

Several times we were stranded in strange places without any money and with our credit cards cancelled - trapped in a hotel that we couldn't check out of because we had no money to check out.

I decided that, somehow, I had to get out of there and go to Hollywood. I had never been to America.

I went out to some advertising agencies and asked if I could do anything.

This was in '79. I got pretty restless there, sitting around with a lot of people sitting around smoking cigarettes and talking about films, but nobody really doing anything.
