Well I was an asthmatic child. So that for most of my childhood I was in bed. Bedridden.

And having suffered for part of the war when I was a child. I was too young to really understand what was going on but one of my favorite pieces of animation now is that Goodbye Blue Sky in The Wall because that deals directly with that period in time.

Being sent to bed is a terrible command to all children, because it means the most public possible humiliation in front of adults, the confession that they bear the stigma of childhood, of being small and having a child's need for sleep.

All the children had to wear a gas mask in case of a gas attack by the Germans. They tried to make the masks like Mickey Mouse faces so the children would like them. But I didn't. They had big ears on them.

And when Roger talks about the frightened ones running away from the bombs, I immediately thought of my days when I was young and I had to wear these gas masks.

I mean when I was working shall we say with Disney, you know they sent me the script for the film Hercules and I had to imagine what all the characters looked like. And to develop those characters, so nothing exists visually when I get the script.
