“We did play around with Ivan, chopping the Leica reel – the filmed storyboard. We would try different music on different bits and try having this thing follow that one, so it didn’t take us long to get it to what we have now. And we had to: we had Columbia Pictures saying, “We’ve got to have this thing by July 1981 or forget it. We might pull out!” So you come up against those sorts of things. Some of it is quite crude.”
