On an Unknown Beach is an intriguing 2016 documentary film from New Zealand. Directed by the talented filmmaker Amiria Randell and produced by Alexander Behse, this thoughtful film is often categorized under the documentary, history and biography genres. Through a combination of storytelling, visually striking footage, and thought-provoking exploration, the film has left an indelible impression on its audience, particularly those with a deep interest in human-nature relationships.

This multifaceted film provides a profound excursion into the unknown, exploring the boundaries of human knowledge where the known meets the unknown. The film is divided into three segments, each part focusing on a different professional field - geologist, sonic artist, and an archaeologist.

Richard Levy is the geologist we meet first. His penetrating gaze is on the bleakly fascinating landscapes of the forgotten regions of New Zealand. From the black sands of Piha to the rich territories of Huntly, the camera follows his journey through geologically intriguing areas, revealing man's often destructive impact on the land. Levy's study on these terrains provides the audience a unique and seldom-seen view of New Zealand, a real tribute to the country's raw beauty and brutal reality.

The second segment introduces us to Bruce Russell, a sonic artist, and musician, whose self-described "anti-music" work is spotlighted. A founding member of the noise band 'The Dead C', Russell introduces us to his philosophy surrounding music and his ideas of creating 'soundscape'. Enclosed in his uniquely constructed room, filled with analog audio devices, Russell creates cacophonic soundscapes, turning noise into his music. Russell's avant-garde sonic experiences provide viewers an alternative lens to perceive art and sound.

The final segment involves the controversial archaeologist, Peter Vangioni, whose interest lies in the field of maritime archaeology. He takes us on an exploration to a shipwreck site underwater, revealing the beauty, mystery, and danger that lie beneath the sea's surface. The film encapsulates Vangioni's passion and dedication towards his profession, blending the excitement of discovery with the historical richness of the sea.

Despite taking place in separate spheres, the film elegantly intersects these stories to shed light on human curiosity at its most raw. Randell brilliantly weaves different stories and environments by using a contemplative narrative style and visual elements that make each sequence a standalone piece of art. Each person's journey highlights a distinct field of exploration, yet together they illuminate the universal human propensity to explore, understand, and ultimately, grapple with the limits of our knowledge.

The film's narrative technique is non-linear and relies heavily on visual storytelling. The slow and silent shots, interspersed with the noise of nature and Russell's experimental music, create an oddly soothing rhythm that sets the tone throughout the film. The use of black and white, as well as saturated color sequences, further enhances the film's unique visual style.

On an Unknown Beach presents a complex tapestry of characters and landscapes, peppered with questions about human existence, our place in the universe, and the nature of knowledge itself. Despite each narrative being seemingly disjointed, as an ensemble, they represent beautifully a collective exploration of the strange, the unseen, and the unknown in our world.

What makes the film truly special is its refusal to spoon-feed the audience with easily digestible narratives. Instead, viewers are actively encouraged to engage in their own explorations and form their own interpretations, much like the protagonists of the film.

On an Unknown Beach is an undeniably contemplative and slow-burning cinematic journey that invites viewers into a profound exploration of space and sound. The critics have praised it as a provocative meditation on our relationship with the environment, the complexities of art, and the process of scientific exploration.

In conclusion, On an Unknown Beach is a must-watch for anyone interested in documentary films that push the boundaries of the genre, providing a unique, immersive viewing experience. With its striking visuals, intriguing characters, and complex themes, it is not merely an excursion into the unknown but a thought-provoking piece about exploration, understanding, and the limits of human knowledge.
