My goal is that after seeing 'Grand Canyon,' every person in the audience will go home knowing they have to conserve water: even something as simple as installing a low-flow toilet or showerhead, or turning off the faucet while they're brushing their teeth.

I didn't leave home until 27. I was an only child raised in Philadelphia by my mother and grandmother. My grandmother controlled the stove. She made a lot of potato meals - mashed potato, potato souffle, potato pancakes. When we didn't have electricity, we ate romantically by candlelight.
