These are all the times Rod Serling says “The Twilight Zone” on camera. It does not include outros since he is off camera for those.
Rod Serling did not appear on screen until the episode “A World of His Own” which is included in this supercut as the first clip. He did not always say “The Twilight Zone” in his intros but he did most of the time. Also, sometimes they would cut away when he said it in which case the clip was not included. Some of the clips are poor quality, that can either be attributed to the poor quality of the files or in some cases episodes being filmed on tape or both.
