5 Controversial 1970s Movies That Would Be Almost Impossible to Make Today

The 1970s produced some of the boldest, darkest and most controversial films in cinema history. Filmmakers were willing to explore violence, obsession, political power and deeply uncomfortable subjects without making their stories easy for audiences to accept. Some of these movies created controversy, while others pushed their productions to extraordinary limits.

Looking back today, five particular films stand out. Their themes were provocative, their filmmaking was fearless, and in some cases, simply getting the movies completed was an enormous challenge. Here are five 1970s movies that would be extremely difficult to make in the same way today.

Deliverance Turned an Outdoor Adventure Into a Nightmare

John Boorman's Deliverance begins with what sounds like a straightforward adventure. Four men from the city travel to canoe the rapids of a river that is destined to be destroyed by a dam.

However, the peaceful journey quickly becomes something much darker. Away from the safety of their everyday lives, the men encounter brutal violence and a frightening environment where nature provides no protection.

The difficult filming conditions added another layer of danger to the production. The movie was filmed in Rabun County, Georgia, where several sequences were physically demanding for the cast.

Jon Voight personally performed some of the most challenging scenes, including climbing a rock face with his bare hands. Burt Reynolds wanted to attempt canoeing down a waterfall, while Ned Beatty was placed in a situation where he even risked drowning during the filming of the rapids.

The pressure surrounding the production also contributed to a violent brawl on set. The combination of dangerous locations, demanding performances and a tense working environment made Deliverance feel like an ordeal both on screen and behind the camera.

Taxi Driver Took Audiences Inside a Disturbed Mind

Martin Scorsese's Taxi Driver, written by Paul Schrader and released in 1976, remains one of the defining examples of the darker side of New Hollywood.

Robert De Niro plays Travis Bickle, a Vietnam War veteran whose life has become increasingly isolated. His insomnia leads him to work as a night taxi driver, putting him in constant contact with the streets of New York.

As Travis spends more time observing the city, his perception of it becomes increasingly distorted. He sees New York as corrupt and filthy, believing that it needs to be cleansed.

What makes the film particularly powerful is that Scorsese does not offer a simple explanation of Travis. Instead of presenting him merely as a monster, the movie places viewers inside the perspective of a deeply troubled and lonely man.

That approach makes Taxi Driver uncomfortable precisely because it refuses to provide easy answers. Its exploration of isolation, obsession and extremism is one reason the film remains such a striking example of 1970s cinema.

Apocalypse Now Nearly Collapsed Before It Was Finished

Few productions demonstrate the risks of 1970s filmmaking better than Apocalypse Now.

Francis Ford Coppola's Vietnam War epic faced serious difficulties before production even properly got underway. Several major studios rejected the project because the Vietnam conflict remained a painful and sensitive subject in the United States.

Coppola ultimately took on a huge amount of the financial risk himself and moved production to the Philippines. What followed became one of cinema's most infamous production stories.

Martin Sheen suffered a heart attack during filming. Typhoon Olga destroyed numerous sets and put Coppola himself in serious danger. Construction of jungle structures also resulted in the death of a worker, while Coppola experienced serious physical problems connected to dehydration and malnutrition.

The chaotic production was later documented in Hearts of Darkness, giving audiences an inside look at how difficult the movie's creation became.

Considering the scale of the project and the risks involved, it is easy to understand why Apocalypse Now represents a filmmaking approach that would be difficult to imagine on a major production today.

A Clockwork Orange Became a Symbol of Controversy

Stanley Kubrick's A Clockwork Orange was another 1970s film that deliberately challenged its audience.

Adapted from Anthony Burgess's novel, the story presents a near-future Britain where teenage violence, known as "ultraviolence," becomes a major problem. The government responds with a disturbing re-education program.

Malcolm McDowell plays Alex, a young man who commits violent acts with his gang. Kubrick presents the brutality through highly stylized and carefully choreographed imagery, creating an unsettling contrast between beautiful filmmaking and disturbing subject matter.

The movie also refuses to make the conflict completely straightforward. Alex's violence is horrifying, but the state's attempt to control him raises equally disturbing questions about power and individual freedom.

The controversy surrounding the film became enormous. British tabloids linked it to incidents of imitative violence, while Kubrick received death threats that also targeted his family.

In 1973, Kubrick personally chose to withdraw the film from distribution in the United Kingdom. It remained effectively unavailable there until his death in 1999.

Salò Pushed Italian Cinema to Its Limits

Pier Paolo Pasolini's Salò, or the 120 Days of Sodom may be the most extreme example on this list.

Released in 1975, shortly after Pasolini's murder, the film adapts the work of the Marquis de Sade and relocates its story to the final period of the Italian Social Republic.

The story follows four powerful men who abduct a group of teenagers and take them to an isolated villa. There, the victims are subjected to an escalating series of humiliations and acts of horrific violence.

Yet beneath its deliberately disturbing surface, Pasolini constructed a political allegory about absolute power. The film examines how unchecked authority can reduce human beings to objects while stripping away their dignity and individuality.

The movie was banned in several countries for extended periods. In the United Kingdom, an uncut version was not approved by the British Board of Film Classification until 2000.

Its extreme subject matter and uncompromising approach make Salò one of the most challenging and controversial films associated with 1970s cinema.

Why This Matters

These five films show why the 1970s remain such a fascinating period in movie history. Deliverance embraced genuine physical danger during production, Taxi Driver explored a disturbing psychological perspective, and Apocalypse Now pushed filmmaking to extraordinary production limits.

Meanwhile, A Clockwork Orange and Salò confronted audiences with controversial ideas about violence, authority and human behavior.

What connects all five is their refusal to make difficult material comfortable. They were not designed to give viewers simple answers or familiar heroes. Instead, they challenged audiences and, in several cases, created controversy far beyond the cinema.

The 1970s Took Risks Few Films Take Today

The idea that these movies "would never be made today" is ultimately a reflection of how unusual their combination of subject matter, creative freedom and production circumstances was.

Each film crossed a different boundary. Some were physically dangerous to produce, some were controversial because of their themes, and others became notorious because of the reaction they generated.

That is precisely why these controversial 1970s movies continue to attract attention. Decades later, they remain reminders of a period when filmmakers were prepared to take enormous creative risks—and sometimes pay an equally enormous price for doing so.
