- “[The Sky Backdrops] were designed specifically by my art director, who's also a pilot, so he's got a lot of knowledge of skies, 'cause it's obviously drawn by a man who knows his clouds. He's up there all the time!”
- ―David Mitton, 60 Minutes Interview
He was also one of the original production designers for "Magic Adventures of Mumfie".
