After the success of their earlier motion picture Master of the World (1961), American International Pictures had planned to make another film based on a Jules Verne story, "In the Year 2889", however this project was later shelved. A few years later, when Larry Buchanan was given the script of AIP's earlier film Day the World Ended (1955) to remake, a new title was needed. Since AIP had already registered the "In the Year 2889" title, it was tacked onto the Buchanan film.
AIP gave director Larry Buchanan the script for Day the World Ended (1955) to use for this film. The result is an almost line-for-line remake.
Shot in 16mm and color and used to pad out one of American International's television syndication packages.
All promotional materials, including the TV Guide, post the title as "Year 2889," but the on screen credits are indeed "In the Year 2889."
Larry Buchanan's 5th Azalea production, completed in May 1967 (shooting began May 14).
