One of my film history professors worked as a dailies hand on a film with Donald, and told us an anecdote how Donald would look at the dailies on a reel-to-reel Steenbeck-style film editor (pre-digital!). When he did this, he would take a jacket an throw it over his head and around the light-box and watch it in seclusion. A man dedicated to his craft!
