Major changes were made to most episodes for syndication. The 60-minute episodes were edited down to 30 minute packages, with major edits to some of the 30-40 minute segments of the original shows. In cases of segments that were only 15-20 minutes in length, these were padded out by adding stock footage, newly shot scenes, and footage from Hollywood movies such as Silent Running (1972) and Fahrenheit 451 (1966). Most musical cues were also replaced for syndication. In order to augment "Night Gallery"'s syndicated run, episodes of The Sixth Sense (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."
