You learn, of course, when you're working with something good, but you also can learn when you're working with things that are not good. You can see the reasons they're not good. I would sometimes suggest what could be done, but essentially say "It isn't worth the bother." So I learned from that process.

When I started I had no knowledge of films whatsoever. I was an engineering major at Stanford. And I found out as a senior that they had two film critics on the Stanford Daily, and they got free passes to all the theaters in Palo Alto. So I thought, I'll do that, and I became a film critic. And then I became interested in films. But I had no time to study anything in that area because I was a senior, just finishing up as engineering.

Somebody who moved up very fast was Jim Cameron, who was a young guy out of - I think he came from Arizona, from some community college there, and he was building model spaceships, on a picture called Battle Beyond the Stars.
