Editing Incubus (1966 film) (section)

==Production==

===Pre-production===
After the [[ABC Television Network]] cancelled producer Leslie Stevens' science fiction series ''[[The Outer Limits (1963 TV series)|The Outer Limits]]'' in 1965, Stevens wrote a horror script to make use of the talents of the ''Outer Limits'' team he had brought together – including cinematographer [[Conrad L. Hall]] and composer [[Dominic Frontiere]] – with an eye to marketing it to art houses.

Stevens and producer Anthony M. Taylor wanted a device to make the film unique, and, to this end, chose [[Esperanto]] as the film's language. The script was translated into Esperanto, and the actors rehearsed for 10 days to learn their lines phonetically, but no one was present on the set to correct their pronunciation during shooting.<ref name=tcmarticle>Miller, John M.

===Filming===
Principal photography took place over 18 days in May 1965. Location shooting took place at [[Big Sur]] Beach and at the [[Mission San Antonio de Padua]] near [[Fort Hunter Liggett]] in [[Monterey County]]. Concerned that the authorities would not grant permission to shoot a horror film in these places, especially the Mission, Stevens concocted a cover story that the film was actually called ''Religious Leaders of Old Monterey'', and showed the script, in Esperanto, but with stage directions and descriptions about monks and farmers.<ref name=tcmarticle />
