"A tale of love, betrayal, and espionage on the eve of war"
Marine officer van Hauen is preparing to depart for war when he makes a devastating discovery: his beloved wife is having a secret affair with the manipulative Count Spinelli. Consumed by jealousy and heartbreak, van Hauen struggles with his duty to country versus his personal turmoil. What the van Hauens remain unaware of is that Count Spinelli's seduction is part of a much larger, sinister plot involving espionage and betrayal. As the officer leaves for the front lines, the web of deceit continues to unravel at home, with potentially catastrophic consequences for both his family and his country. The film builds to a dramatic confrontation where hidden motives are revealed and loyalties are tested in the shadow of impending war.
This was Benjamin Christensen's directorial debut and also marked his first major acting role. The film was shot during the early months of 1914, just before the outbreak of World War I, which gave its military themes particular resonance. Christensen took an innovative approach to lighting and camera movement for the time, using shadows to enhance the mysterious atmosphere. The production utilized real naval uniforms and locations to add authenticity to the military setting.
The Mysterious X was produced during a pivotal moment in European history, released in October 1914, just two months after the outbreak of World War I. This timing gave the film's themes of military duty, betrayal, and espionage immediate relevance to audiences across Europe. Denmark remained neutral during WWI, but the war loomed large in Danish consciousness, making films about military conflict particularly resonant. The Danish film industry was experiencing a golden age in the early 1910s, with Nordisk Film becoming one of Europe's most productive studios. This period saw Danish cinema gaining international recognition for its technical innovation and sophisticated storytelling. The film's exploration of psychological themes and moral ambiguity reflected the growing modernist sensibilities in European art and literature, moving away from the clear moral dichotomies of earlier cinema.
The Mysterious X represents a crucial milestone in Danish cinema history, marking the emergence of Benjamin Christensen as one of Denmark's most important early filmmakers. The film demonstrated that Danish cinema could compete with international productions in terms of technical sophistication and psychological depth. Its success helped establish Denmark as a major force in European film production during the silent era. The film's innovative use of lighting and shadow to create atmosphere influenced the development of film noir aesthetics in later decades. Christensen's approach to psychological thriller elements in this film foreshadowed his later masterpiece 'Häxan' (1922), which would become one of the most influential documentary-style horror films ever made. The film also contributed to the development of the espionage thriller genre, predating many of the conventions that would become standard in spy cinema.
The production of The Mysterious X was marked by Christensen's meticulous attention to detail and innovative directorial approach. As a first-time director, he insisted on complete creative control, which was unusual for the period. Christensen spent months researching naval protocols and uniforms to ensure authenticity. The film's most challenging scenes involved the maritime sequences, which required careful coordination with the Danish Navy. Christensen developed a reputation during filming for his demanding standards, often requiring multiple takes to achieve the precise emotional tone he wanted. The relationship between Christensen and co-star Karen Sandberg was reportedly tense off-camera, which some critics believe enhanced the authenticity of their on-screen tension. The film's innovative use of lighting, particularly in scenes involving Count Spinelli, required custom-built lighting rigs that were considered revolutionary for Danish studios at the time.
The cinematography by Louis M. Danvers was groundbreaking for its time, featuring innovative use of chiaroscuro lighting to create atmosphere and psychological tension. Danvers employed techniques that were unusual in 1914, including dramatic shadows to emphasize the mysterious nature of Count Spinelli's character. The film's naval sequences featured sweeping camera movements that conveyed the scale of maritime operations. Interior scenes used carefully composed shots to create a sense of claustrophobia and tension, particularly in scenes involving the van Hauen household. The film also experimented with subjective camera angles, placing the viewer in the psychological perspective of different characters. Danvers's work on this film influenced the visual style of later Danish productions and contributed to the development of cinematic techniques for expressing psychological states.
The Mysterious X featured several technical innovations that were advanced for Danish cinema in 1914. The film employed sophisticated double exposure techniques for dream and memory sequences, creating layered visual effects that enhanced psychological storytelling. The production used artificial lighting systems that were custom-built for the film, allowing for dramatic shadow effects that were rarely seen in Danish productions of the era. The naval sequences required innovative camera mounting techniques to achieve smooth movement on ships at sea. The film's editing was particularly advanced for its time, featuring cross-cutting between parallel action lines to build suspense. Christensen also experimented with varying shot lengths to control pacing, using longer takes for emotional moments and rapid cutting for scenes of tension. These technical achievements helped establish Danish cinema's reputation for innovation during the silent era.
As a silent film, The Mysterious X was originally accompanied by live musical performance. The original score was composed by Danish composer Emil Reesen, who created a sophisticated orchestral arrangement that emphasized the film's dramatic and mysterious elements. The score featured leitmotifs for different characters, particularly a sinister theme for Count Spinelli that recurred throughout the film. In Danish theaters, the music was performed by small orchestras or talented pianists who could adapt Reesen's compositions. For international releases, different musical arrangements were created to suit local tastes. Modern restorations of the film have featured newly composed scores by contemporary musicians specializing in silent film accompaniment, with some using period-appropriate instruments to recreate the original 1914 sound.

Contemporary Danish critics praised The Mysterious X for its sophisticated narrative structure and Christensen's compelling performance. The Danish newspaper Politiken called it 'a triumph of national cinema' and particularly noted the film's technical innovations. International critics were equally impressed, with German film publications highlighting Christensen's directorial debut as evidence of Danish cinema's growing sophistication. Modern film historians consider the work a significant achievement in early psychological cinema. The British Film Institute's silent film archive describes it as 'ahead of its time in its exploration of psychological motivation and moral ambiguity.' Contemporary critics have noted how the film's themes of betrayal and hidden agendas resonate with modern concerns about surveillance and espionage.
The Mysterious X was a commercial success in Denmark, playing to packed houses in Copenhagen theaters for weeks. Audiences were particularly drawn to the film's suspenseful narrative and Christensen's charismatic performance. The film's timely release during the early months of World War I created additional public interest, with many viewers finding parallels between the on-screen drama and real-world events. International audiences also responded positively, with the film performing well in Germany, Sweden, and Norway. In the United States, where it was released under the title 'The Mysterious X,' it found success with art-house audiences who appreciated European cinema's sophistication. Contemporary audiences at revival screenings continue to respond to the film's suspense and psychological depth, with many noting how effectively it maintains tension despite its age.
The Mysterious X has been partially preserved with approximately 75% of the original footage surviving. The Danish Film Institute holds a restored version that was completed in 1998 using surviving prints from various international archives. Some scenes, particularly certain transitional sequences, remain lost and are reconstructed through still photographs and intertitle cards. The restored version features color tinting based on original distribution notes, with blue tones for night scenes and amber for daylight sequences. The film has been digitized in 4K resolution as part of the Danish Film Heritage preservation project. While not completely intact, the surviving version maintains the narrative coherence and visual impact of Christensen's original vision.
