Frequently Asked Questions

Most impactful documentary ever?

Blackfish (2013) is frequently cited as one of the most impactful documentaries ever made. The film about orca captivity at SeaWorld triggered a collapse in the company's stock price, led to the cancellation of its orca breeding program, inspired new animal welfare legislation, and caused numerous corporate sponsors to withdraw. Al Gore's An Inconvenient Truth (2006) is another strong contender, winning the Oscar and an Emmy while helping elevate climate change as a political priority worldwide.

Best nature documentary?

Planet Earth (BBC, 2006) narrated by David Attenborough is widely considered the greatest nature documentary ever made. It was the first nature series filmed entirely in high definition, took five years to produce across 62 countries, and won multiple BAFTA and Emmy Awards. Its 2016 sequel Planet Earth II and Blue Planet II (2017) are also frequently ranked among the best, with Blue Planet II famously sparking the 'Attenborough effect' — a dramatic shift in public awareness about plastic pollution in the oceans.

Has a documentary ever changed laws?

Yes — several documentaries have directly influenced legislation. Blackfish led California to pass the California Orca Protection Act in 2016, banning orca breeding and theatrical shows. Making a Murderer prompted Wisconsin lawmakers to introduce criminal justice reform bills. An Inconvenient Truth influenced climate policy debates globally. Super Size Me contributed to McDonald's discontinuing its Super Size menu in 2004, just weeks after the film premiered at Sundance.
