The Relentless Eye: A Cinematic Analysis of the One-Shot Film and Sam Mendes's 1917

This blog task is assigned by Prof. Dilip Barad on studying one-shot films and understanding various concepts pertaining to one-shot films and film studies.

Introduction

In traditional cinematic grammar, the cut (découpage) is the fundamental unit of narrative construction. Through montage, directors fragment time and space, synthesizing disparate images to construct meaning, manipulate pacing, and guide the spectator's emotional response. The edit provides cognitive relief—a visual punctuation mark that allows the audience to process information from a safe, curated distance. However, the "one-shot" or continuous take deliberately subverts this foundational syntax. By discarding the cut, filmmakers strip away the psychological safety net of montage, transforming the screen into a relentless, unblinking witness to reality.

Within a film studies framework, the one-shot is not merely a logistical gimmick or a display of technical bravado; it is a profound structural choice that alters the audience's phenomenological relationship with the moving image. It enforces temporal continuity, trapping the viewer in the immediate present of the narrative. This blog explores the theoretical underpinnings and technical mechanics of the one-shot format. By dissecting specific cinematic techniques—such as blocking, character color coding, and spatial integrity—and applying them to a rigorous analysis of Sam Mendes's World War I epic 1917 (2019), we can understand how the continuous take elevates film from passive observation to visceral, kinetic empathy.

The Theoretical Framework: My Understanding of the One-Shot Film

My initial encounter with this demanding format occurred recently during my postgraduate film studies unit. I watched the gripping Netflix limited series Adolescence—a viewing experience that fundamentally reshaped my understanding of screen narratives. Seeing an entire story unfold in real-time without a single visible edit across hour-long episodes was a staggering revelation. It was this specific encounter with the raw, unblinking tension of Adolescence that first introduced me to the concept and mechanics of the one-shot format. The series completely shifted my academic perspective, prompting me to investigate exactly how removing the safety of the cut alters our cognitive and emotional reception of moving images.

To analyze the one-shot film requires moving beyond a mere description of its unbroken nature and examining how it functions as a distinct semiotic system. When the traditional language of editing is removed, the filmmaker must rely entirely on the internal dynamics of the frame.

Temporal Continuity and Realism

• The Rejection of Montage: While early theorists like Sergei Eisenstein argued that meaning is generated through the collision of shots (montage), theorists like André Bazin championed the long take. The one-shot film embodies Bazin's pursuit of cinematic realism. By maintaining continuous screen time, the film aligns perfectly with diegetic story time. The audience experiences the weight of every passing second, creating an inescapable temporal claustrophobia.
• Sculpting in Time: This format literalizes Andrei Tarkovsky's concept of filmmaking as "sculpting in time." The director cannot artificially compress a grueling journey or skip over moments of mundane tension. The continuous timeline forces the spectator to endure the psychological burden of waiting, anticipating, and surviving alongside the protagonist.

Guiding the Gaze: Techniques of the Continuous Frame

Without the ability to cut to a close-up to emphasize a detail, or cut to a wide shot to establish geography, how does a director guide the audience's eye? Educational breakdowns, such as the In Depth Cine video essay "How To Shoot A Scene With A Single Camera," illuminate the complex mise-en-scène required to achieve this.

• Character Color and Wardrobe Contrast: In a constantly moving frame, a subject can easily be lost against a chaotic background. As discussed in video analyses of the format, directors heavily rely on character color coding. By assigning the protagonist a specific color palette that contrasts sharply with the production design, the filmmaker uses color theory as a substitute for an edit. The viewer's eye is naturally drawn to the contrasting hue, allowing the camera to remain wide while maintaining clear visual focus on the character's trajectory.
• Dynamic Blocking and Depth of Field: The physical choreography of actors (blocking) must work in perfect tandem with camera movement. Characters move across the z-axis (towards and away from the lens) to artificially create the effect of a close-up or a wide shot within a single take. Rack focusing—shifting the focal plane from foreground to background—directs the audience's attention without ever breaking the visual continuity.
• Environmental Cues and Lighting: Lighting transitions replace the scene transition. A character stepping from a cool, dimly lit interior into a harsh, brilliantly exposed exterior signals a narrative shift. These practical lighting changes are meticulously timed to guide the viewer's emotional state, acting as the invisible cuts of the one-shot film.

The True vs. The Simulated Take

• The Authentic Unbroken Take: Films like Sebastian Schipper's Victoria (2015) are captured in a single, genuinely unbroken rolling of the camera. This introduces an element of live, high-wire theatricality. The diegetic tension on screen is mirrored by the practical tension of the production, as a single error requires a complete reset.
• The Simulated Take (Trompe l'œil): Films like Alejandro G. Iñárritu's Birdman (2014) employ hidden edits—whip pans, crossing through dark shadows, or digital plate blending—to stitch multiple takes into a seamless illusion. From a structuralist perspective, this approach is fascinating: it utilizes the highly artificial manipulation of digital effects to achieve an aesthetic of pure, uninterrupted realism.

An Analytical Case Study: Sam Mendes's 1917

Sam Mendes's 1917 stands as a monumental achievement in the simulated one-shot format. The narrative follows two young British soldiers, Schofield and Blake, tasked with delivering a message across enemy lines to prevent a massacre. The continuous take is not an aesthetic afterthought; it is the structural spine of the film, designed to strip the viewer of their omniscient distance and plunge them into the trenches.

Structural Urgency and Kinetic Empathy

• Eliminating the Psychological Buffer: War films typically rely on rapid, chaotic editing to convey the disorientation of combat. 1917 does the inverse. By locking the audience into a continuous perspective, Mendes eliminates the psychological buffer of the cut. There is no escape to a safer vantage point. The audience is bound to Schofield and Blake, sharing their exhaustion, their terror, and their claustrophobia. This creates a profound state of kinetic empathy; the physical exertion of the characters translates directly into the somatic experience of the viewer.
• The Inescapability of Consequence: When a character is suddenly killed, there is no cutaway to a reaction shot to soften the blow, nor a time-lapse to process the grief. The trauma occurs in the same unbroken breath as the preceding quiet conversation. The one-shot format mirrors the sudden, senseless, and abrupt finality of death on the Western Front, denying the audience the cinematic comfort of traditional mourning.

Reverse-Engineered Mise-en-Scène

• Spatial Contiguity: Because pacing could not be dictated in the editing room, it had to be built into the physical environment. The production design of 1917 was reverse-engineered from the script's temporal demands. If a dialogue exchange between the corporals required three minutes of walking, the physical trench had to be constructed to exact proportional length to accommodate that specific duration.
• The Roving Subjective Camera: Cinematographer Roger Deakins utilized specialized equipment, such as the ARRI Trinity stabilization rig, to maintain spatial contiguity. The camera operates in a state of fluid subjectivity. It tracks behind the soldiers, adopting their limited field of vision, then gracefully floats in front of them, turning the audience into an obstacle they must push past. This constant spatial negotiation keeps the frame dynamic and psychologically active.

Color Theory and Nightmarish Illumination

• The Écoust Sequence: The use of lighting and character color reaches its zenith during the nighttime sequence in the ruined French town of Écoust-Saint-Mein. As Schofield navigates the skeletal ruins, the only illumination comes from German magnesium flares arcing across the sky. The stark, sweeping shadows act as a massive, environmental shutter, plunging the screen into darkness before erupting into a hellish, monochromatic orange.
• Visual Isolation: In this sequence, Schofield's dirt-caked, earth-toned uniform contrasts with the blinding, artificial light of the flares and the subsequent burning church. The color palette shifts from the muddy, desaturated browns of the trenches to a stark, high-contrast nightmare. The camera's refusal to cut heightens the surrealism of this environment. We watch the light shift in real-time, mapping out the geography of danger without a single expositional edit.

Diegetic Sound as the Invisible Edit

• Spatial Audio Design: In the absence of visual cuts, sound design dictates the geography of the film. 1917 relies almost entirely on diegetic sound to warn the audience (and the characters) of incoming threats. The distant rumble of artillery, the whine of a dogfight overhead, or the sudden snap of a tripwire are mixed spatially. Sound replaces the visual cue; the audience hears a threat off-screen before the continuous camera slowly pans to reveal it, building an agonizing sense of anticipation.

Conclusion

The one-shot film is a demanding semiotic exercise that forces both the filmmaker and the spectator to relearn the language of cinema. By abandoning the cut, directors must master the intricate orchestration of blocking, character color coding, and lighting transitions to maintain narrative clarity within an unyielding temporal frame.

Sam Mendes's 1917 proves that when applied with rigorous thematic purpose, the simulated continuous take transcends technical novelty. It becomes a tool of unparalleled immersion. By anchoring the camera to the relentless forward momentum of its protagonists, the film collapses the distance between the screen and the audience, proving that the most devastating way to witness the horrors of war is to strip away the safety of the edit and simply refuse to look away.
