On animals and ethics

Earthlings (2005, Shaun Monson, narrated by Joaquin Phoenix) — a look at pets, food, clothing, entertainment and research. Graphic. Dominion (2018, Chris Delforce) — an Australian documentary using aerial drone, hidden-camera and handheld footage. Graphic. Pignorant (2024, Joey Carbstrong) investigates UK pig farming. Land of Hope and Glory (2017) examines UK animal farming. Both also contain distressing footage.

Most viewers say what changed them was seeing it, not reading it.

On health

Forks Over Knives (2011) — the Esselstyn / Campbell case for whole-food plant-based diets against heart disease. The Game Changers (2018, Louie Psihoyos; executive producers include James Cameron and Arnold Schwarzenegger) — plant-based athletes and performance. What the Health (2017) — broader claims about chronic disease; useful as a starting point, check sources before quoting.

On the environment

Cowspiracy (2014) — the climate case against animal agriculture, with the personal-investigation framing that made it viral. Seaspiracy (2021) — the ocean version: industrial fishing, bycatch, dolphin and whale meat. Eating Our Way to Extinction (2021) — biodiversity, ocean, climate, all in one place; narrated by Kate Winslet.

"A good documentary does something an essay cannot: it shows."

On the workers and the system

Slaughterhouse: The Task of Blood (2005, Brian Hill) — a graphic BBC Two documentary about workers and animal slaughter at a family-run abattoir in Oldham, England.

How to use this list

Three rules of thumb. One, start with the topic that already worries you — climate-anxious viewers begin with Cowspiracy; health-curious viewers with Forks Over Knives or What the Health; ethics-led viewers with Earthlings or Dominion. Two, watch with someone if you can — the conversation afterwards does more than the film. Three, the graphic ones (Earthlings, Dominion) work best as a single viewing; don't loop them.

What documentaries change, and what they don't

Evidence that documentaries cause lasting dietary change is mixed. A 2021 paper by Stanford-affiliated researchers reported three randomised experiments with a different documentary; it did not find reduced reported meat and animal-product consumption when potential social-desirability bias was minimised. A film may prompt reflection, but neither a viewing nor a follow-up meal guarantees behaviour change.

Reading alongside the watching

For depth, pair films with books: Eating Animals (Foer), This Is Vegan Propaganda (Earthling Ed), Why We Love Dogs, Eat Pigs, and Wear Cows (Joy), How Not to Die (Greger), We Are the Weather (Foer). Animal Equality and Mercy For Animals publish undercover investigations. For policy, read FAO's Livestock's Long Shadow (2006) and the EAT-Lancet Commission's 2019 report, Food in the Anthropocene.

How to host a film night that actually changes minds

Pick the audience's film

Start with health-curious friends and Forks Over Knives or The Game Changers; start with climate-minded ones and Eating Our Way to Extinction. The wrong film for the room is worse than no film.

Feed them well first

A generous plant-based meal before the credits roll can make the evening welcoming and offer a practical example. Treat it as hospitality, not a proven way to outperform the film's persuasive effect.

Skip the lecture afterwards

Let the film speak. Ask one open question — 'what surprised you?' — and listen. The conversation people lead themselves into is the one they remember.

Have one easy next step ready

A recipe link, a beginner's guide, or an invitation to next month's dinner gives interested viewers a practical next step. Let people move at their own pace.

Practical questions

Are these on Netflix?

Availability varies by country and changes over time. Check each film's official viewing page rather than assuming Netflix or Prime carries it. Dominion offers free viewing through its official website, and Earthlings provides viewing information on its official site.

Will I be traumatised?

Some of these are difficult. Watch with a friend, take breaks, and don't binge them. Earthlings and Dominion are the most graphic; The Game Changers and Forks Over Knives are not.

Have any been criticised?

What the Health, Cowspiracy and Seaspiracy have all been challenged on specific statistics and interpretations. Assess each claim separately against current research rather than treating a film's overall argument as verified.

Anything for kids?

73 Cows can be a gentler starting point. For nature documentaries, including David Attenborough's work, check the specific film's age rating and content advice: some include predation, animal injury or distressing environmental themes. Preview anything intended for children.

Asked about the films

Are the graphic ones really necessary?

No one needs to watch graphic footage to make informed choices. Hopeful films and graphic exposés reach different audiences, and no single approach works for everyone. Offer clear content warnings, respect viewers' preferences and use disturbing footage only with informed consent.

What if a film has been criticised for inaccuracy?

Check disputed claims individually rather than assuming either that an entire film is accurate or that every argument is wrong. Animal agriculture contributes substantially to emissions, and appropriately planned plant-based diets can improve some cardiometabolic outcomes. That does not validate every disease claim in a film. Use films as conversation starters, not citation lists.

Where can I legally stream them?

Start with each film's official website for authorised viewing links. Dominion offers free viewing at dominionmovement.com; Earthlings lists viewing information through Nation Earth. Netflix, Prime, Vimeo and other services vary by country, title and date, so confirm current availability.

What's a good non-graphic film for a child or teen?

Consider 73 Cows as a gentler starting point, but preview it and check suitability for the child's age. The Game Changers includes adult themes, and environmental documentaries may include distressing imagery. Cowspiracy includes animal-killing footage and is not a reliably non-graphic choice.

What the evidence says

Documentaries change behavior — but only under specific conditions the research now describes well.

  1. Cowspiracy shifted viewers' knowledge and intentions in a controlled study.

    A randomised study summarised by Faunalytics compared Cowspiracy with an episode of Planet Earth among daily meat-eaters aged 19–32. Cowspiracy improved environmental knowledge, attitudes toward eating less meat and intentions to cut back. These are short-term measures, not proof of lasting dietary change.[1]

  2. Advocacy videos do not always beat a control.

    In Faunalytics' 2020 campus experiment, 25.8% ordered a meatless meal after a meat-reduction video and 18.9% after a go-vegetarian video. The difference was only marginally significant, and neither video clearly outperformed its matched control.[2]

  3. Study design strongly affects measured impact.

    Research summarised by Faunalytics shows how demand effects and selective participation can inflate the apparent effect of a documentary. Judging films by viewers' stated intentions alone can overstate their impact on what people actually eat.[3]

After the film

Watching is the first step. If a film stayed with you, the seven-day starter is the practical next move.

Key takeaways

  • One hour of the right film reaches people that a hundred pages of text won't.
  • The strongest films for the ethical case (Dominion, Earthlings) show what industry hides.
  • For climate and health, Cowspiracy, Seaspiracy, Forks Over Knives and The Game Changers cover the core cases.
  • Different films land differently — screen the one that matches your audience's starting concern.
