Blue Harvest was the title of the film ruse used to ensure secrecy and disguise the 1981 – 1983 production of Star Wars Episode VI: Return of the Jedi, the third installment of the Star Wars film series. The supposed film was alleged to be an upcoming horror film with the tag line "Horror Beyond Imagination." The title was used in all areas where deemed necessary. The Blue Harvest ruse, credited to producer Howard Kazanjian, was very thorough, emblazoning the fictitious film's logo on a wide range of film production items including shirts, caps, coats, buttons, signs, invoices and stationery. The Blue Harvest façade did give a bit of a wink and nod to its true purpose however, as the supposed film's logo (intentionally or unintentionally) used the distinctive Star Wars logo lettering style.
In particular the ruse was employed during location filming in Yuma, Arizona. The filming took place in the dunes over the Thanksgiving holiday, where there was a reported crowd of 35,000 dune buggy enthusiasts. Despite erecting a chain link fence, employing a huge security force, and dodging myriad press inquiries, in the end, approximately sixty fans saw through the ruse and refused to leave until they obtained a few autographs and photos.
The Blue Harvest front was not only used during the principal photography for Return of the Jedi, but was also adopted in other areas such as a retro T-shirt that was made by ILM in the 1990s, a cardboard mailer tube to disguise the shipments of Revenge of the Jedi (the original title for the film) posters, an episode of the 1985-1987 Star Wars animated series Star Wars: Ewoks, and even a popular Star Wars fanzine. The name Blue Harvest is widely known by Star Wars fans today. While filming The Empire Strikes Back, Lucas found that services would increase their charges based on the speculated high budget. The false title prevented this for Return of the Jedi.
