Heraldo de Madrid - The 20 Most Shocking Documentaries Ranked: From Elizabeth Holmes to Man on Wire

The upcoming UK release of Nathan Fielder’s highly anticipated documentary about Elizabeth Holmes has prompted a re-evaluation of the non-fiction genre’s capacity to shock and affect audiences. As attention turns to this latest entry in the canon of corporate exposés, it is useful to examine the broader landscape of documentaries that have previously defined the boundaries of truth-telling on screen.

The history of documentary cinema is often marked by myths of audience reaction, such as the persistent anecdote that viewers fled their seats in terror when the Lumière brothers’ 1960s short film depicted a locomotive approaching the camera. While historians note this story likely never occurred, it underscores the medium’s enduring power to create visceral reactions through the presentation of reality.

Modern filmmakers have developed sophisticated techniques to achieve similar effects without relying on crude re-enactments. Keith Maitland’s account of the 1966 mass shooting at the University of Texas utilized rotoscoped animation to revitalize the re-enactment format. By tracing over archival footage, Maitland created an emotional immediacy comparable to a thriller, leaving viewers with an elegiac sense of loss rather than mere spectacle.

In the realm of true crime, which has seen a deluge of violent narratives in the 21st century, some documentaries offer relief by focusing on psychological mystery rather than physical brutality. Chilean director Maite Alberdi’s work explores the story of Ale, a Mexican mother who, after suffering three miscarriages, convinced her husband she was pregnant. The film investigates whether Ale was also a child-snatcher, using this bizarre long con to probe the metaphysical question of how much any person can truly be known.

The genre also excels at revealing hidden subcultures. Marc Singer’s work in New York City unearthed the existence of "mole men," homeless individuals living in abandoned subway tunnels beneath Penn Station. Set against DJ Shadow’s atmospheric compositions, the film provides a grimly transfixing look at urban deprivation, initiating viewers into a realm of life previously invisible to the public.

Corporate fraud remains a potent subject for documentary filmmakers. An early work by Alex Gibney from the mid-2000s shocked audiences with revelations about the collapse of a major US energy company and its profit-falsifying practices. At the time, such scale of boardroom cynicism seemed unprecedented; today, its insights feel like a precursor to the tech-industry chicanery and post-truth environment that characterize contemporary discourse.

Werner Herzog’s filmography frequently explores hubris and madness, yet his 1982 documentary Fitzcarraldo stands out for its meta-narrative. The film chronicles Herzog’s own attempt to drag a steamboat over a mountain in Peru to make his epic feature. It captures the director’s difficult decisions, including whether to let Indigenous people kill his leading man, Klaus Kinski, and includes the now-iconic "the birds are in misery" monologue, blending documentary with the chaos of its own production.

Other works push the boundaries of cinematic language itself. Dziga Vertov’s Man With a Movie Camera sought to create an international visual language separate from literature and theater. Through slo-mo, double exposure, split screens, and rhythmic editing, Vertov created a mosaic of Moscow, Odesa, and Kyiv that functions as a self-reflexive celebration of the medium.

Godfrey Reggio’s Koyaanisqatsi similarly uses a monumental city-symphony structure to depict human civilization. Juxtaposing neolithic drawings with rocket launches and accelerating through stages of modern life set to Philip Glass’s score, the film offers a visual essay on the trajectory of society, inviting comparisons to the current age of artificial intelligence.

Experimental approaches also define some of the genre’s most memorable entries. A narration-free montage aboard a Massachusetts trawler immerses viewers in the sensory experience of commercial fishing. Without commentary, the film presents hurtling anchors, churning water, and fish being processed, creating a sense of merging with the vessel’s consciousness.

Adventure documentaries often rely on the physical stakes of their subjects. The story of Alex Honnold’s unroped climb of El Capitan in Yosemite National Park captures attention not just through the feat itself, but through the ethical questions it raises regarding his girlfriend, Sanni McCandless, and the potential for directors to heighten risk for cinematic effect.

Similarly, Touching the Void recounts the survival saga of climbers Simon Yates and Joe Simpson in the Andes. Director Kevin Macdonald frames the narrative as a moral litmus test, focusing on Yates’ decision to cut the rope to save his own life and Simpson’s subsequent crawl over ice and glacial scree to safety.

The genre also grapples with historical trauma. Alain Resnais’s Shoah provides a devastating warning about the Holocaust through a concise tour of atrocity sites, calmly laying out how humanity surrenders to its worst instincts. Joshua Oppenheimer’s The Act of Killing takes this further by empathizing with the perpetrators of the 1960s Indonesian anti-communist genocide. By allowing death-squad members to re-enact their deeds in the style of film noir and musicals, Oppenheimer exposes the links between state power, moral self-justification, and the authorship of history.

Other films focus on personal tragedy and identity. Kurt Kuenne’s tribute to his murdered friend Andrew Bagby is a partisan work that demonstrates the force of love surrounding Bagby, even as it faces criticism for its treatment of Bagby’s ex-girlfriend, Shirley Turner, who was accused of killing him in a murder-suicide.

James Marsh’s Man on Wire recounts Philippe Petit’s 1974 high-wire walk between the Twin Towers. The film uses heist-like pacing to tell the story behind the iconic image of Petit standing upright in the void, highlighting the daredevil’s audacity and the inhuman scale of the feat.

Andrew Jarecki’s All Good Things explores the domestic enigma surrounding Arnold Friedman and his son Jesse, questioning whether they were victims of a local moral panic or perpetrators of violence. The film suggests that the biggest mysteries often lie within one’s own family.

Bart Layton’s The Imposter investigates the case of Nicholas Barclay, a Texas teenager who disappeared in 1994 and reappeared three years later as Frédéric Bourdin, a French man with different eye color. The film explores the psychological needs driving such a scam and the family’s willingness to accept the impostor.

Finally, Claude Lanzmann’s Shoah remains a nine-hour testament to bearing witness to the Holocaust, offering psychological understanding through survivor accounts. These works, alongside the upcoming Elizabeth Holmes documentary, demonstrate the documentary form’s ability to challenge perception, expose truth, and explore the complexities of human experience.
