About 90 percent of the score for the incredibly strange 1966 film Incubus -- starring William Shatner, with all dialogue spoken in Esperanto -- was tracked in from existing music originally composed for the Outer Limits TV series by Dominic Frontiere. Outer Limits creator Leslie Stevens was the director of this film, and Frontiere composed a few bits of incidental music that couldn't be covered by existing Outer Limits cues.
I'm unreasonably fascinated by this film and its music and set out to reconstruct the score, which has turned out to be a more complex puzzle than I imagined. Music editor John Caper Jr took four of Frontiere's Outer Limits scores and edited, overlaid, rearranged, and occasionally remixed the music to fit the picture. This Main Titles cue, for instance, is taken from the episode "Controlled Experiment," but chopped into multiple pieces, moved around, and even looped at the beginning.
These screen caps are meant to highlight the other great feature of the film, Conrad Hall's moody cinematography. I've taken to calling it Ingmar Bergman's The Outer Limits. A truly unusual movie.
