Deep in the jungle of Central Vietnam, lies a magnificent underground kingdom. Hang Son Doong which translates as “mountain river cave”, is the largest cave passage in the world and a place of spectacular beauty. With more people having climbed Everest than visited Son Doong, its pristine charm has remained undisturbed for millions of years. In 2014, Son Doong’s future was thrown into doubt when plans were announced to build a cable car into the cave. With many arguing that this would destroy its delicate eco-system and the local community divided over the benefits this development would bring, the film follows those caught up in the unfolding events. Beautifully shot and scored, “A Crack In The Mountain” is a powerful exposé about how both good and bad intentions can ultimately lead to one of the world’s greatest natural wonders being trampled for money. As well as inspire those who care about our natural heritage to fight to protect it.

The Land of Jacques Cartier (1963)
Did Cartier dream of making a country from this land of a million birds? In his records of his exploration he certainly marvelled at seeing the great auks that have since disappeared from Isle aux Ouaiseaulx, the razor-bills and gannets that are gone from Blanc-Sablon, and the kittiwakes from Anticosti, all the winged creatures of all the islands which he described as being "as full of birds as a meadow is of grass". And that's not even counting the countless snow geese.

Tell Me Lies (1968)
Adapted and directed by Peter Brook from the Royal Shakespeare Company’s ‘production-in-progress US’, this long-unseen agitprop drama-doc – shot in London in 1967 and released only briefly in the UK and New York at the height of the Vietnam War – remains both thought-provoking and disturbing. A theatrical and cinematic social comment on US intervention in Vietnam, Brook’s film also reveals a 1960s London where art, theatre and political protest actively collude and where a young Glenda Jackson and RSC icons such as Peggy Ashcroft and Paul Scofield feature prominently on the front line. Multi-layered scenarios staged by Brook combine with newsreel footage, demonstrations, satirical songs and skits to illustrate the intensity of anti-war opinion within London’s artistic and intellectual community.

With their radical but strictly non-violent gatherings in public spaces, they call for a "Rebellion against extinction" to prevent ecological collapse.

The Ants and the Grasshopper (2021)
Anita Chitaya has a gift: she can help bring abundant food from dead soil, she can make men fight for gender equality, and maybe she can end child hunger in her village. Now, to save her home in Malawi from extreme weather, she faces her greatest challenge: persuading Americans that climate change is real. Traveling from Malawi to California to the White House, she meets climate sceptics and despairing farmers. Her journey takes her across all the divisions that shape the USA: from the rural-urban divide, to schisms of race, class and gender, and to the American exceptionalism that remains a part of the culture. It will take all her skill and experience to help Americans recognise, and free themselves from, a logic that is already destroying the Earth.

Herbicide Trials (1984)
In 1983, fifteen Cape Breton, Nova Scotia, landowners went to court to stop the spraying of herbicides by the local subsidiary of a Swedish multinational on forests adjacent to their properties. They found that the testimony of scientists and the support of public opinion, both here and abroad, were not enough to win their case. The film shows their ordeal and the landmark Sydney trial. Concerns raised included potential conflict-of-interest situations where a government must protect citizens' health while supporting certain kinds of industry; the relative value of the political and judicial processes in mediating social problems; and the need for a public forum for debating environmental issues. The film contains outstanding footage from chemical-industry films of the 1950s and recent material about Vietnam veterans affected by Agent Orange.
