premise: "Klaatu barada nikto" is a phrase that originated in the 1951 science fiction film "The Day the Earth Stood Still". The humanoid alien protagonist of the film, Klaatu (Michael Rennie), instructs Helen Benson (Patricia Neal) that if any harm befalls him, she must say the phrase to the robot Gort (Lockard Martin). In response Gort relents from destroying the Earth and resurrects Klaatu from death.
hypothesis: Klaatu barada nikto is never translated in the film.
reason: The text doesn't say that "Klaatu barada nikto" was translated in the film, only that it is a phrase that needed to be said. The algorithm must have assumed the meaning was given in the film.
