20 minutes in length, these were padded out by adding stock  footage, newly shot scenes, and footage from Hollywood movies such as Silent  Running and Fahrenheit 451. Most musical cues were also replaced for  syndication. In order to augment "Night Gallery"s syndicated run, episodes  of "Sixth Sense, The" (1972) were edited down to 30 minutes, had new  introductions by Rod Serling tacked on, and were added to the syndicated run  of "Night Gallery."
