Arrow Video's 4K Limited Edition of 'Incubus' impresses with a stunning restoration in 2160p featuring HDR10 and Dolby Vision, though limited by the source's French burn-in subtitles and occasional detail issues, achieving remarkable tonal richness in its black and white cinematography.
Audio: 73
The 4K UHD release of 'Incubus' features an unusual Esperanto LPCM Mono audio track, offering a thin yet serviceable sound with a notable hiss and Dominic Frontiere’s score sounding tinny at times. The dialogue and effects improve upon these elements despite occasional burnt-in French subtitles, all complemented by optional English and Esperanto subtitles.
Extra: 93
The Extras of the "Incubus" 4K UHD Blu Ray offer a well-curated selection, featuring multiple commentaries, a newly reconstructed isolated score track in LPCM 2.0, and engaging documentary featurettes on Esperanto's cinematic history. The presentation is technically proficient with commendable clarity and synchronicity.

Despite 'Incubus' being a visually stunning film with Conrad Hall's remarkable cinematography and featuring William Shatner's memorable performance, its potential is undermined by a thin narrative and heavy reliance on Esperanto as a gimmick, leaving intriguing themes largely unexplored in its brief runtime.

Arrow Video's 4K UHD release of "Incubus" offers an intriguing restoration, despite some constraints due to the loss of the original camera negative. The film is presented in 2160p with a HEVC/H.265 encode, supporting HDR10 and Dolby Vision, in a 1.85:1 aspect ratio. A notable distinction for this release is the absence of an accompanying 1080p Blu-ray, a choice which has implications for evaluating its visual fidelity when compared to its 1080 counterpart. Restored by Le Chat Qui Fume, the 4K version captures a remarkable improvement in tonal ranges and contrast, lending new depths to the monochromatic palette that underscore its visual intensity.
The restoration utilizes the last known surviving 35mm French print as its source, inadvertently embedding unavoidable burn-in subtitles. While these subtitles subtly intrude into the lower frame, they do not significantly detract from the viewing experience. The cinematography's high contrast, augmented by HDR and Dolby Vision, ensures that the film's stylistic choices in opticals and transitions do not overly compromise fine details—though in some scenes without complex transitions, marginal improvements are evident.
The most compelling aspect of this 4K release is its enhanced range of black and white tones, particularly evident in the oceanic scenes. These comparisons draw on references such as Howe's work in "Seconds," highlighting a thoughtful homage to classic cinema. Though some may debate the chosen aspect ratio, the presentation generally maintains compositional integrity. This restoration, despite its constraints, reintroduces "Incubus" to audiences with a visually rich experience capable of revisiting the cinematography with fresh appreciation.

The 4K UHD Blu-ray of "Incubus" offers an intriguing audio presentation with its LPCM Mono Esperanto track, a rare feature that deserves particular acknowledgment. Though the uniqueness of the language may enhance thematic immersion, the audio quality itself presents limitations. Dominic Frontiere's score, sourced from "Outer Limits", can sound tinny, revealing a thinness that might not satisfy audiophiles seeking depth. Additionally, a detectable hiss accompanies some musical cues. However, the sound effects and dialogue maintain clarity, crucial for preserving the captivated attention of audiences throughout the film's narrative journey. Optional subtitles are available in English and Esperanto, with burnt-in French subtitles providing a unique multinational perspective.
The technical aspects of the audio indicate a careful restoration effort that may not have entirely achieved contemporary excellence but still respects the authenticity of the original material. Handling such a rare language track inherently possesses significant challenges, and while it does not compare to today's high-resolution multi-channel audio formats like Dolby Atmos or DTS:X, the inclusion of unique language offerings showcases a commitment to preserving cultural and historical context. The track's integrity complements the vintage cinematic experience rendered by the film's visual aesthetic.
While this Esperanto track on "Incubus" delivers an experience somewhat bound by its spectral limitations, it remains an auditory curiosity enhanced by its historical novelty. The mix endeavors to respect and accurately portray the original intentions within the boundaries of available technology, offering a nostalgically tinted presentation. Audiophiles interested in classic or unique soundtracks may find value, despite its limitations, through this Blu-ray release.
Extras: 93

Additionally, the newly reconstructed isolated score track in LPCM 2.0 highlights the film's musical intricacies. The release enhances the viewing experience with informative featurettes that delve into the film's rare cinematic language and its historical context. Notably, viewers have the option to explore an open matte feature with additional frame information. Complemented by a comprehensive insert booklet, the extras are carefully curated to enrich the understanding of "Incubus" and its place in cinema history.

"Incubus," known for being the first mainstream feature extensively shot in the constructed language Esperanto, is a unique blend of art-house ambition and horror mystique. The film stars a pre-Trek William Shatner and centers on the surreal narrative of succubi, particularly Allyson Ames' character Kia, within a fantastical, healing village. Kia, a bored demon, longs to ensnare a truly righteous man, represented by Shatner's character Marc. This unusual plot spins a web of supernatural themes involving redemption, ethical corruption, and soul entrapment.
Shot by veteran cinematographer Conrad Hall, the film exudes an atmospheric European style reminiscent of Mario Bava’s and John Moxey’s works. Its woozy gothic vibe is beautifully captured through black-and-white cinematography that elevates the thin narrative to a more engaging viewing experience. Despite these visual strengths, comparisons to "The Outer Limits" are inevitable due to its storytelling limitations—highlighted by a scant 74-minute runtime. While it toys with deep themes such as love's possession and the corruption of purity, the film fails to adequately elaborate on these concepts, leaving audiences wanting more than the tantalizing glimpses provided.
Esperanto adds an additional layer of intrigue, although mostly seen as a marketing unusuality than a narrative driver. The performances, particularly from Shatner, maintain an engaging presence despite phonetic challenges with the language. The movie retains a peculiar charm due to its unique premise and striking visuals but struggles to balance its aspirations with coherent delivery. "Incubus" ultimately emerges as a fascinatingly flawed piece—haunted more by its potential unrealized than its triumphs achieved, offering a memorable yet incomplete supernatural experience.
Total: 75
"Incubus," a peculiar cinematic artifact from the 1960s, finds new life in Arrow's 4K UHD Blu-ray release. This intriguing film, shot entirely in Esperanto and featuring a young William Shatner, is more of a cultural curiosity than a hidden gem. The narrative is simple, and the film's brevity limits the exploration of its supernatural romance theme. However, the stylish execution and atmospheric aura make it an intriguing piece for enthusiasts of esoteric cinema.
Arrow's 4K transfer does an exceptional job of making the best out of a challenging source material. The visuals are enhanced with a strong HDR/Wide Color Grading, bringing an unexpected vibrancy to the screen while respecting the original aesthetic. This release is further enriched by a robust suite of supplementary materials that delve into the film's unique linguistic choice and production history, providing audiences with a deeper understanding of this unconventional project.
In conclusion, "Incubus" on 4K is recommended for those drawn to cinematic oddities or dedicated Shatner fans who wish to experience one of his earliest works. While not without its flaws, the film's distinctiveness and the extensive extras make it a compelling addition to any adventurous movie collection. Arrow has once again delivered a high-quality package that celebrates an unusual slice of film history.

PlotIn a mystical world where evil and good spirits vie for human souls, a succubus named Kia seeks to corrupt pure souls. She lives with her sister Amael near a healing spring reputed to purify the souls of those who drink its waters. The spring attracts many people, often in desperation, seeking its reputed powers. Hungry for more powerful prey, Kia dismisses weaker and morally corrupt men she easily tempts, wishing instead to challenge herself by ensnaring a truly virtuous soul. Her sights set on Marc, a noble soldier who has recently encountered the miraculous spring, she devises a plan to seduce him.
Marc, recovering from war and purifying himself at the spring, exemplifies purity and strength, making him an enticing target for Kia's quest. However, when the two meet, Marc grows suspicious of Kia’s allure, sensing something awry despite falling easily into conversation with her. As they spend more time together, Kia begins to experience foreign emotions that challenge her duty as a succubus. This unexpected shift leads her to question her intentions and the very essence of her existence, while Marc remains unaware of her true nature. At this critical juncture, Kia confronts an array of conflicting desires and loyalties that threaten the stability of her supernatural realm and her own identity. The forces of light and dark collide in an intense struggle that tests the boundaries of redemption and damnation.
