I remember the first thing I ever saw Duvall in. It was the 25th anniversary of The Twilight Zone and the producers showed a never-before-aired hour long episode that had been colorized. Around 1983-84. It starred a young Duvall playing a quiet office worker that spent his daily lunch time at a local museum where he became increasingly infactuated with a doll house and the beautiful young lady inside. Great show.
I remember that...the Twilight Zone did a season of hour-long shows that are rarely seen in syndication.
