Top 20 Documentaries That Shocked Audiences Worldwide

#20: “The Cove” (2009)

Directed by Louie Psihoyos, this documentary debuted to instant controversy, especially in Japan. “The Cove” was an exploration of Japan’s dolphin hunting drive in Taji, its brutality exceeding that of even whale hunting. Psyhoyos recorded secret footage of dolphins being herded into a cove, with the youngest sold to marine parks and the rest killed. After the film’s release, Taji became the center of global controversy, with activists arriving to protest this animal cruelty. Taji leaders insisted their methods were lawful, and SeaWorld representatives denied purchasing dolphins from this drive. Later documentaries were released rebutting many claims from the film. “The Cove” definitely hit a nerve.

#19: “Dear Zachary: A Letter to a Son About His Father” (2008)

This award-winning film, directed by Kurt Kuenne, is a very personal one. “Dear Zachary” follows the murder of Kuanne’s close friend, Andrew Bagby, who was shot five times. Bagby’s girlfriend, Shirley Jane Turner, was arrested as a suspect while pregnant. She eventually gave birth to Bagby’s child, Zachary. Bagby’s parents tried to get custody of Zachary, but a judge denied them, ruling Turner was not a danger to others. Turner went on to take her own life and that of her child’s. This case sparked outrage and inspired a huge campaign to change federal bail laws to protect children and consider their safety in these criminal cases. This film opened many people’s eyes.

#18: “Icarus” (2017)

This Icarus flew dangerously close to the sun. Director Bryan Fogel’s investigation into the world of illegal doping led him to uncover a truly enormous sports scandal. Russian scientist Grigory Rodchenkov provided evidence that Russia was trying to cheat in the Olympics with a state-sponsored program. Not only that, but Rodchenkov revealed that he himself covered up the Russian team’s urine samples for clean ones during the 2014 Winter Olympics. After an independent agency verified his claims, Rodchenkov was placed in witness protection. Amid worldwide outrage, the Russian government denied all involvement. Talk about corruption.

#17: “Food, Inc.” (2008)

This film is not for the faint of heart or the weak of stomach. “Food, Inc.” is an exposé of the cruel and environmentally unsustainable practices of corporate farming. The film claims the meat production of chicken, beef, and pork involved the abuse of both animals and the human employees that work in the factories. The documentary also criticizes the use of petroleum products in agriculture, advocating for stronger food safety laws. Multinational food companies declined being interviewed for the documentary. Once the film was released to ensuing public outrage, they issued responses to the documentary’s claims. It’s eye-opening, all right.

#16: “Surviving R. Kelly” (2019-23)

An unflinching investigation into the abuse allegations against popular R&B singer Robert “R.” Kelly, this Lifetime documentary changed the game for good. In this series, several women testified they had been assaulted by Kelly when they were underage, with the abuse stretching over decades. Famous musicians like Lady Gaga, Celine Dion, and Ciara condemned him and removed their collaborations from streaming services. Shortly after the documentary’s release, new allegations came out, and Kelly was finally arrested. In 2021 and 2022, he was convicted and sentenced to more than 30 years in prison. Justice at last was served.

#15: “Blackfish” (2013)

Directed by Gabriela Cowperthwaite, this documentary follows the story of an orca named Tilikum, held captive at Seaworld. After being captured in 1983 and harassed by other captive orcas, Tilkum went on to display aggressive behavior. He attacked multiple trainers and even killed three people. “Blackfish” also posits that SeaWorld’s claim that their captive orcas’ lives were comparable to their wild counterparts was false. In response, SeaWorld alleged that the documentary misrepresented how the company trained and cared for the orcas. Either way, the public response was seismic, causing SeaWorld’s revenue to drop significantly. New legislation was proposed, including updating the Animal Welfare Act of 1966. The truth will out.

#14: “White Light/Black Rain: The Destruction of Hiroshima and Nagasaki” (2007)

This sobering documentary follows the testimonies and even lives of fourteen Japanese survivors of the atomic bombings of Hiroshima and Nagasaki. Mostly children or teens at the time, many survivors eventually fell sick to the radiation. Heartbreakingly, they even blamed themselves for their illness. The film also includes the testimony of four Americans involved in the attacks, including one who claimed to have witnessed the bombing firsthand. Released on the 62nd anniversary of the attacks, the film was nominated for the Grand Jury Prize at the 2007 Sundance Film Festival, forcing us to confront hard truths about war time atrocities.

#13: “Citizenfour” (2014)

Americans’ knowledge of unethical government surveillance is largely due to this critically-acclaimed documentary. Directed by Laura Poitras, the film follows Poitras as she receives a strange email by one Citizen Four, claiming to have evidence for the illegal wiretapping practices by the National Security Agency. Poitras, along with Glenn Greenwald and Ewen MacAskill, went to Hong Kong to meet with Citizen Four. This turned out to be former NSA contractor Edward Snowden, now a whistleblower resisting extradition attempts to the U.S. “Citizenfour” had global impact outside the U.S., spreading newfound awareness of governmental surveillance and data collection worldwide. This won’t be easily forgotten.

#12: “Leaving Neverland” (2019)

Whatever your feelings on legendary singer and entertainer Michael Jackson, this HBO documentary certainly had a massive impact. “Leaving Neverland” follows the testimony of two men who claimed to have been abused by the late singer when they were children. The response was huge on all levels, both the critical reception and backlash, with radio stations pulling Jackson’s music and removing his name from marketing. The Jackson estate meanwhile sued HBO for violating a non-disparagement clause. Other documentaries rebutting “Leaving Neverland”’s claims were released, claiming Jackson was a victim of yellow journalism. Talk about having a massive impact.

#11: “The Missing Picture” (2013)

This French film, directed by Rithy Panh, follows the impact of the Cambodian genocide on its people and society. Using both news footage and clay animation, the documentary follows the historical events that led to the Khmer Rouge’s rise, re-creating its atrocities. Panh himself lived through the Khmer Rouge’s regime as a child, with him and his family taken to a labor camp. He escaped to Thailand and eventually France. Critically acclaimed, “The Missing Picture” provides powerful insight into how genocidal regimes decimate human rights, erase identities, and suppress cultural heritage. It’s an ugly picture, but a true one.

#10: “Earthlings” (2005)

The realities of animal abuse are brouight into sharp focus in this powerful documentary. “Earthlings” was directed by Shaun Monson with narration by Joaquin Phoenix, chronicling the cruel practices of pet stores, animal experimentation, puppy mills, and factory farms. It’s an eye-opening exposé, drawing explicit parallels between animal abuse and the anti-social prejudices of racism and sexism. “Earthling’s” impact was seismic. It even played an unexpected role in the Lutsk hostage crisis, with the hijacker demanding the Ukrainian president recommend the film to everyone on social media. Talk about getting the word out.

#9: “One Child Nation” (2019)

The disastrous effects of China’s one child policy are explored in this searing film, directed by Nanfu Wang and Jialing Zhang. Implemented to curb China’s population growth, the policy led to forced abortion and sterilization practices, as well as child abandonment and even human trafficking. Baby girls comprised the bulk of the victims, with most families favoring baby boys, leading to a marked gender ratio imbalance. Wang herself even had a family member who abandoned her cousin in 1989 and details their unsuccessful attempts at finding her. It is a devastating film exposing the many-faceted horror government policy can inflict.

#8: “Waltz with Bashir” (2008)

This animated documentary directed by Ari Folman was a controversial one. In it, Folman meets with his old friend, Boaz, once an Israeli soldier in the 1982 Lebanon War. Boaz recounted how he would kill the dogs so that they would not alarm villagers to their presents. Although Folman, too, was an Israeli soldier during the war, he cannot recall memories of his experience there. It becomes clear that Folman had suppressed memories of the massacre, with his mind protecting himself from the complete knowledge of his complicity. Chilling but honest, the film premiered to both critical acclaim and backlash, becoming banned in Lebanon and other Arab countries. The truth is elusive, but it still hurts.

#7: “13th” (2016)

For a film that sheds light on the U.S.’s prison-industrial complex, look no further than this award-winning documentary. Director Ava DuVernay explores the U.S.’s massive prison industry and its roots in slavery, particularly Jim Crow laws that criminalized minor offenses for former slaves, effectively disenfranchising them. This racialized criminalization continues to the present day with the War on Drugs, the over-policing of marginalized communities, and the rise of private prison contractors. The film was a wild success, garnering both acclaim and criticism, holding up a mirror to the dark heart of U.S. politics.

#6: “The Killing of America” (1981)

For a Japanese perspective on American violence, this Sheldon Renan-directed film is a must-see. The film explores the rise of American serial killers, school shootings, and the effects of famous assassinations, particularly John F. Kennedy’s and John Lennon’s. Some killers, the documentary posits, have even become celebrities and pop culture icons. Released in Japan in 1981 and later the United States in 1982, the documentary received a mixed reception, with some critics feeling that it does not go deep enough in its sociological analysis of U.S. violence. Still, it is a gruesome mirror to American brutality that still feels unfortunately relevant.

#5: “Abducted in Plain Sight” (2017)

Directed by Skye Borgman, this documentary’s surreal story is a chilling one. In 1970s Idaho, 12-year-old Jan Broberg was kidnapped by family friend Robert Berchtold not only once, but twice. When Berchtold lied to Broberg’s parents, claiming Jan had become a sex worker who was into substance use, her mother’s reply is a shockingly understated, “Oh, dear.” The family’s odd response drew outrage from viewers, although Jan herself defended her parents as victims of Berchtold’s manipulations. Stranger than fiction, “Abducted in Plain Sight” opens our eyes to the realities of grooming and manipulation and the consequences of blind trust.

#4: “The Look of Silence” (2014)

A companion piece to his game-changing “The Act of Killing,” director Joshua Oppenheimer returns to the 1965 Indonesian Communist Purge, this time through the victims’ perspectives. Upon watching Oppenheimer’s 2012 film, optometrist Adi Rukun is stunned to recognize the men who killed his brother. Rukun visits and interviews the killers themselves, which include his uncle, none of whom express remorse. Rukun’s response is the titular look of silence. Horrific, disturbing, and downright frustrating, “The Look of Silence” is a deep dive into the impacts of murder on the individual and society, as well as the psyche of killers involved in such crimes.

#3: “Bowling for Columbine” (2002)

Granted, Michael Moore’s “Fahrenheit 9/11,” a sharp exploration of the flimsy excuses and downright lies that led to the 2003 invasion of Iraq after the 9/11 attacks, is certainly memorable. But this seminal documentary by him tackles one of the biggest problems in America today: Gun violence, particularly school shootings. The film investigates the shooting at Columbine High School in 1999, with Moore trying to understand how this massacre happened and America’s high violent crime rate in general. A searing indictment of America’s permissive culture of gun violence, the conclusions drawn are still very much timely and relevant even decades later.

#2: “The Act of Killing” (2012)

Director Joshua Oppenheimer’s landmark film sent shockwaves throughout the world. In this film, Oppenheimer asks some of the participants of the Indonesian mass killings of 1965-66 to reenact their crimes. Many of the killers were gangsters or from paramilitary groups, particularly the Pancasila Youth group, who confessed to both their murders and even assault of young girls. One of them, Anwar Congo, surmised he has killed as many as a thousand people and confessed that he still gets nightmares over his actions. “The Act of Killing” sparked praise, discussion, and controversy, as well as leading to Adi Rukun identifying the murderers of his brother. The banality of evil has never been so, well, banal.

#1: “Shoah” (1985)

There are many excellent and influential Holocaust documentaries, including 1956’s short but impactful “Night and Fog.” But for a truly thorough exploration of one of Europe’s biggest atrocities, Claude Lanzmann’s nine-hour epic “Shoah” is a requisite watch. In this film, Lanzmann explores the death camps in Treblinka, Auschwitz-Birkenau, the extermination camp of Chelmno, and the ghetto in Warsaw. Lanzmann includes countless testimonies from survivors, perpetrators, and bystanders alike. Unused material for the film was eventually made into five other feature-length films. Universally praised and included in the Memory of the World international register in 2023, “Shoah” is a witness to the worst of humanity.
