upset by the production overrunning. For the second episode, Hartnell recorded voice clips on 26 June, as he was on holiday during its recording. Footage of the Viking ship in the second episode was sourced from a 1949 BBC Newsreel titled The Land of the Vikings. For the third episode, Butterworth ad-libbed a comment about converting kilometres to miles. The final episode was recorded on 2 July 1965. Reception Broadcast and ratings The serial was broadcast on BBC1 in four weekly parts from 3 to 24 July 1965. The first episode was broadcast later than usual—6:55p.m. instead of 5:40p.m.—due to an extended edition of the preceding program Grandstand covering the Henley Regatta and Wimbledon Championships final. The final broadcast accidentally omitted Camfield's directing credit by fading out early; Camfield complained to Wiles, who issued a memo requesting that this not be allowed in future.

BBC Enterprises continued to market the serial in the 1970s, but sales had diminished by 1977 and the first, third, and fourth episodes were subsequently wiped. All four episodes were discovered in Nigeria in October 1984 and returned to the BBC by February 1985; they were discovered to have been cut, with some missing scenes. A twelve-second clip from the fourth episode remained missing from the complete prints of the serial, as it was removed by censors; it depicted a scene where Vikings are stabbed to death.
