Incubus is a black and white horror film originally released in 1965 and later restored in 2001. Incubus was directed by Leslie Stevens[?] and stars a pre-Star TrekWilliam Shatner. The entire film was shot and directed entirely in the constructed languageEsperanto. It was done in Esperanto to create an eerie other-worldly feeling, and dubbing into other languages has been prohibited by the director. The 2001 DVD includes subtitles in English and French and the restoration was funded by the Sci Fi Channel[?]. Most English speakers have given the film good ratings and reviews while Esperanto speakers are generally disappointed by the dreadful pronunciation in the film.
It is a common myth that Incubus was the first Esperanto film[?], but Angoroj appeared in 1964, one year before Incubus.
