### Plot
At a NASA gathering of government and military officials, mission director Dr. Zimmerman boasts that the Stardust spacecraft will travel faster than the speed of light on its maiden journey to the farthest star. Senator Milburn refuses to send astronauts on so dangerous a mission, so aerospace engineer Tom Trimble is instructed to build a human-like robot instead; Tom constructs the machine, Hermes, in his own image and teaches it lessons about being a man.[4](https://catalog.afi.com/Film/57126-UNIDENTIFIED-FLYING-ODDBALL?cxt=filmography)
Trimble is sent to the cockpit just before takeoff to fix a last-minute technical problem, but a bolt of lightning strikes and the ship launches prematurely with only him aboard. Traveling faster than light, it races back through time and lands in England in the year 508, during the reign of King Arthur.[5](https://openresearch-repository.anu.edu.au/server/api/core/bitstreams/33f14212-7925-48da-8a27-921f30e31ec1/content) Tom befriends the maiden Alisande and makes an enemy of the knight Sir Mordred, who with the wizard Merlin is plotting to dethrone the king. Tom and Hermes pass off 20th-century technology as sorcery to defeat the scheme, and Tom eventually returns to his own era, deciding to go back for Alisande after discovering that a stowaway goose aboard the ship has not aged at all.[3](https://tv.apple.com/ca/movie/unidentified-flying-oddball/umc.cmc.2p2ajxo3og4718l4c4wv9xyl3) • [5](https://openresearch-repository.anu.edu.au/server/api/core/bitstreams/33f14212-7925-48da-8a27-921f30e31ec1/content)
## Production
[Principal photography](https://www.edgepedia.org/principal-photography) began 10 July 1978 in England and was scheduled for ten weeks, running into mid-September. The production filmed on location at [Alnwick Castle](https://www.edgepedia.org/alnwick-castle), a medieval fortress in [Northumberland](https://www.edgepedia.org/northumberland) near the North Sea.[1](https://catalog.afi.com/Film/57126-UNIDENTIFIED-FLYING-ODDBALL) Working titles included *The Spaceman and King Arthur*, *The Spaceman in King Arthur's Court*, and *King Arthur and the Astronaut*.[1](https://catalog.afi.com/Film/57126-UNIDENTIFIED-FLYING-ODDBALL) Ron Goodwin composed the score, recorded at Anvil Studios, and Paul Beeson was director of photography.[1](https://catalog.afi.com/Film/57126-UNIDENTIFIED-FLYING-ODDBALL) Buena Vista Distribution Co., Inc. handled theatrical distribution in the United States.[1](https://catalog.afi.com/Film/57126-UNIDENTIFIED-FLYING-ODDBALL)
## Place in the Connecticut Yankee tradition
The film belongs to a long line of adaptations of Twain's novel, in which a modern visitor arrives in Camelot with knowledge of the future. Earlier feature versions were *A Connecticut Yankee at King Arthur's Court* (1920), *A Connecticut Yankee* (1931), and *A Connecticut Yankee in King Arthur's Court* (1949); Disney's version adds the space-age premise of a faster-than-light spacecraft in place of Twain's blow to the head.[1](https://catalog.afi.com/Film/57126-UNIDENTIFIED-FLYING-ODDBALL) • [6](https://www.notcoming.com/reviews/unidentifiedflyingoddball) A 1995 Disney film, *[A Kid in King Arthur's Court](https://www.edgepedia.org/a-kid-in-king-arthurs-court)*, returned to the same novel, with [Ron Moody](https://www.edgepedia.org/ron-moody) reprising his role as Merlin from *Unidentified Flying Oddball*.[1](https://catalog.afi.com/Film/57126-UNIDENTIFIED-FLYING-ODDBALL)
One scholarly survey of the novel's adaptations places the 1979 film, *A Kid in King Arthur's Court*, and *Bugs Bunny in King Arthur's Court* (1977) so far from the original in nearly every respect that "adaptation" is too strong a word, since none of Twain's own characters appear in them.[7](https://imagetextjournal.com/the-many-sides-of-hank-modifications-adjustments-and-adaptations-of-mark-twains-a-connecticut-yankee-in-king-arthurs-court/) The film's opening credits do, however, list Mark Twain with a writing credit.[8](https://sunfoxreviews.com/2025/02/06/unidentified-flying-oddball-1979/)
## Reception
Contemporary and later critical response was mixed. Metacritic records a Metascore of 66 from four reviews, two positive and two mixed: Time Out called it "an intelligent film with a cohesive plot and an amusing script" and one of Disney's better science fiction efforts, while the Washington Post found the plot predictable but noted some funny lines.[9](https://www.metacritic.com/movie/unidentified-flying-oddball/critic-reviews/) On IMDb the film holds a rating of 5.2/10 from about 1,600 users.[10](https://www.imdb.com/title/tt0080062/ratings/) A retrospective review notes that several critics at the time compared its special effects unfavorably with *Star Wars*, and that the film came up a bit short of its budget at the box office.[8](https://sunfoxreviews.com/2025/02/06/unidentified-flying-oddball-1979/)
Common Sense Media describes the film as a time-traveling adventure with moments of peril and mild violence, including a scene in which Tom is about to be burned at the stake before escaping, and recommends it for ages 9 and up.[11](https://www.commonsensemedia.org/movie-reviews/unidentified-flying-oddball) The spacecraft prop from the film was later displayed at the Blackgang Chine theme park on the [Isle of Wight](https://www.edgepedia.org/isle-of-wight).[12](https://www.netflixmovies.com/unidentified-flying-oddball-1979) The film was released on DVD by [Walt Disney Studios Home Entertainment](https://www.edgepedia.org/walt-disney-studios-home-entertainment) on August 3, 2004, and is available on Disney+.[13](https://www.dvdtalk.com/reviews/review/12006) • [14](https://www.justwatch.com/us/movie/the-spaceman-and-king-arthur)
