Incubus is a 1966 American black-and-white horror film directed by Leslie Stevens and featuring William Shatner in a leading role. Unusually for a Hollywood production, the film's dialogue is performed entirely in Esperanto and it was released with the Esperanto title Inkubo. Because of its language choice, unusual atmosphere and troubled distribution history, Incubus has become a frequent subject of cult interest and film-historical discussion. More on the film

Overview and creative aims

Shot in a shadowy, expressionistic style, Incubus was intended as a mood piece rather than a conventional studio thriller. Leslie Stevens—best known for his work in television and as creator of genre series—staged the story to emphasize ritual, dread and dream logic. The decision to use Esperanto, a constructed international language, was reportedly chosen to create a feeling of estrangement and universality, so that the film would not be tied to any single national idiom.

Production and technical details

The movie was filmed in California during 1965. Contemporary accounts indicate a modest schedule and budget; production has been described as brisk, lasting a few weeks. Incubus was photographed in black and white to heighten contrast and gothic atmosphere. William Shatner, then an actor still establishing his career prior to his breakout television role, is the most widely recognized member of the cast. The ensemble performed their lines in Esperanto rather than in English, a factor that affected how the film was marketed and distributed. Production notes

Loss, rediscovery and restoration

Following its initial screening, Incubus received very limited distribution and for many years was believed to be lost. Only a French distribution print survived circulation for some time, and the film was effectively unavailable to general audiences for decades. A copy was eventually located in France, and after preservation work a restored version circulated in 2001, bringing renewed attention from cinephiles and scholars interested in rare and unusual films.

Reception, legacy and notable points

At the time of its release the film did not achieve commercial success and was rarely screened outside a few territories. Over the years it has gained a reputation as a curiosity and a study in mid-20th-century experimental genre filmmaking. It is frequently cited as one of the very few feature films made entirely in Esperanto, which gives it particular interest for linguists and fans of constructed-language culture. Reports of misfortunes that affected some cast and crew after production have contributed to an aura of mystery and talk of a so-called "curse," though such accounts are anecdotal and often exaggerated in retellings.
