Rebus-Film Nr. 1 is an innovative German animated short film designed as an interactive theater experience. The film was presented in two parts - shown before and after the main feature - with the first part presenting visual clues to six crossword puzzle words and the second part revealing the answers. The animated character Mr. Rebus serves as the audience's guide, walking viewers through a series of visual puzzles that include clips of a party scene, an Asian country, a European city, table games, winter activities, and bullfighting. The film incorporates dynamic montages of street scenes and spinning objects to enhance the visual storytelling. Title cards throughout encourage active participation from theatergoers, making this an early example of interactive cinema that blurred the line between passive viewing and audience engagement.

Created during the height of German Expressionist cinema, this film represents a departure from the dark, dramatic style typical of the period. Paul Leni, known for his work on 'Waxworks' (1924), brought his visual expertise to this more lighthearted educational format. The film utilized a combination of animation techniques including cut-out animation and limited cel animation, which was innovative for German cinema at the time. The production was designed specifically for theatrical exhibition as an interactive program element, requiring theaters to show it in two separate parts to maintain the puzzle-solving suspense.
Rebus-Film Nr. 1 was produced in Germany during the Weimar Republic period (1919-1933), a time of extraordinary artistic and cultural ferment despite economic instability. The mid-1920s marked the golden age of German cinema, with UFA producing some of the most influential films in history. This period saw the rise of German Expressionism in film, characterized by dramatic visual stylization and psychological depth. Crossword puzzles had recently been introduced to Europe from America and were experiencing a surge in popularity, making them a perfect subject for a contemporary film. The film's interactive nature reflected the era's fascination with new forms of entertainment and audience participation, which also included radio call-in shows and audience voting competitions. Germany's film industry was also experimenting with new formats and technologies, including early sound experiments and various attempts to enhance the theatrical experience beyond traditional narrative films.
Rebus-Film Nr. 1 represents an important but often overlooked milestone in the history of interactive media and educational cinema. As one of the first films designed specifically to engage audiences in problem-solving activities, it anticipated later developments in game-based learning and interactive entertainment. The film demonstrates how early filmmakers were already exploring ways to make cinema a more participatory medium, decades before the advent of video games and interactive digital media. Its use of animation for educational purposes also foreshadowed the later development of educational animation and corporate training films. The film's preservation of the crossword puzzle format in cinematic form provides valuable insight into popular culture and entertainment trends of the 1920s. Additionally, it represents a rare example of lighthearted, commercial content from Paul Leni, who is primarily remembered for his dark, Expressionist works.
The production of Rebus-Film Nr. 1 took place at UFA's studios in Berlin during a period of intense creative experimentation in German cinema. Paul Leni, who had established himself as a master of visual design with films like 'Waxworks,' applied his Expressionist sensibilities to this more commercial format. The animation team employed a combination of techniques, including traditional hand-drawn animation for Mr. Rebus and photographic collage elements for the visual clues. The film's interactive nature required careful coordination with theater owners, who had to agree to present the film in two parts with appropriate timing. The production team worked closely with crossword puzzle designers to ensure the clues were neither too difficult nor too simple for average moviegoers. The film's success led to discussions about creating a regular series of similar interactive shorts, though the concept was ahead of its time in terms of audience expectations and theater logistics.
The cinematography of Rebus-Film Nr. 1 employed a variety of innovative techniques for its time. The film combined traditional animation with photographic elements, creating a mixed-media aesthetic that was relatively uncommon in 1920s cinema. The visual clues were presented through carefully composed shots that utilized both close-ups and wider angles to ensure clarity for the audience. The montages of street scenes and spinning objects demonstrated the influence of Soviet montage theory, with rapid cuts and dynamic camera movements creating visual rhythm. The animation of Mr. Rebus used limited cel animation techniques, which were more efficient than full cel animation but still allowed for smooth character movement. The film's visual style was influenced by German Expressionism in its use of dramatic lighting and bold contrasts, though applied to a more lighthearted subject matter than typical Expressionist films.
Rebus-Film Nr. 1 achieved several technical innovations for its time. The film pioneered the concept of interactive cinema, requiring audience participation to fully experience the content. Its two-part structure, designed to be shown before and after a main feature, was an innovative approach to program formatting that encouraged audience retention. The combination of animation and live-action footage in a single educational context was technically advanced for 1925. The film's use of visual puzzle-solving through cinema demonstrated an early understanding of how visual media could be used for educational and entertainment purposes simultaneously. The clear visual communication of abstract concepts through imagery represented an achievement in visual storytelling techniques. The film also demonstrated early understanding of audience psychology and engagement, using the natural human desire to solve puzzles as a driving force for viewer participation.
As a silent film, Rebus-Film Nr. 1 would have been accompanied by live musical performance in theaters. The score was likely provided by the theater's house organist or pianist, who would improvise or use suggested musical cues to match the on-screen action. The music would have needed to adapt to both the animated sequences and the photographic elements, creating appropriate moods for each visual clue. The interactive nature of the film might have required musical cues that signaled when audiences should begin discussing the clues. While no specific musical scores or cue sheets for this film have survived, typical German theater music of the period would have included popular songs, classical excerpts, and original compositions tailored to the film's needs.

Contemporary German film critics praised Rebus-Film Nr. 1 for its innovative approach to audience engagement and its clever use of animation. Trade publications noted its potential as a regular program element that could enhance the theater-going experience. Critics particularly appreciated the film's departure from the heavy, serious tone that dominated much of German cinema at the time. The technical execution of the animation and the clarity of the visual puzzles were also commended. However, some critics questioned whether the format could sustain audience interest over multiple installments. Modern film historians have rediscovered the film as an important precursor to interactive media, with scholars citing it as an early example of gamification in cinema. The film is now recognized as a significant artifact in the history of educational and interactive entertainment.
The film was reportedly popular with German theater audiences of the mid-1920s, who enjoyed the novelty of participating in solving the crossword puzzle. Moviegoers appreciated the break from traditional narrative films and the opportunity to engage their minds actively during the cinema experience. The two-part format effectively maintained audience interest, with many patrons reportedly discussing possible answers during the intermission. The character of Mr. Rebus became somewhat recognizable to regular cinema patrons. However, the interactive nature of the film also meant that its success depended heavily on the theater's presentation and the audience's willingness to participate. Some reports suggest that the format worked better in smaller, more intimate theaters where audience members could more easily discuss the clues together.
The preservation status of Rebus-Film Nr. 1 is uncertain, as with many German short films from the 1920s. Some sources suggest that copies may exist in European film archives, particularly in Germany's Bundesarchiv or at the Friedrich Wilhelm Murnau Foundation. However, the film is not widely available for viewing, suggesting that either preservation is incomplete or access is restricted. The film's status as a supporting program element rather than a main feature may have contributed to fewer copies being preserved. Restoration efforts for German cinema of this period have primarily focused on feature films, leaving many shorts and program elements in limbo. Film historians continue to search for surviving copies of this innovative work.
