Quoted from Ericpinballfan:Robert Duvall has the claim of the only color to sneek into an episode. He falls in love with a doll in a doll house and at end of episode he is now in the house in a 2 min color scene.
Quoted from wolverinetuner:I haven’t seen all the Season 4 episodes. I imagine the color scene stood out quite a bit!
Quoted from acupunk12:I think that it’s edited out now. I’m going to have to check this out
Quoted from Rdoyle1978:It didn't air with the color originally. It was added as a "bonus" when the episode was re-aired "for the first time!" in the 80s. The color bit was part of the Ted Turner-type colorization starting out at that time. You remember it better than it actually was
That was the syndicated Twilight Zone Silver Anniversary Special from '84 hosted by Patrick O'Neal (he did season 5's "A Short Drink From A Certain Fountain," also in that special). I still have a VHS of it in storage somewhere. And yes, the colorizing was terrible even back then...
