After the original run, NBC syndicated it to local stations, where it proved successful financially through the mid-1960s. NBC also marketed the series overseas; by 1964, it had been broadcast in 40 foreign markets. NBC created a feature-length (89-minute) motion picture condensation. The feature-length version was narrated by Alexander Scourby who replaced Leonard Graves, the narrator of the 26-part series. NBC made a distribution deal with United Artists and the film debuted in mid-1954. NBC also prepared another, 79-minute, condensation for broadcast, and it debuted on 29 December 1960 in a 90-minute evening slot as part of NBC's "Project Twenty" ("Project XX") series, which itself was established in 1955 as an offshoot of original "Victory at Sea" production unit.
