La Soufrière (film): La Soufrière – Warten auf eine unausweichliche Katastrophe ("La Soufrière – Waiting for an Inevitable Disaster") is a 1977 West German documentary film in which German director Werner Herzog visits an island on which a volcano is predicted to erupt.  The pretext of this film was provided when Herzog "heard about the impending volcanic eruption, that the island of Guadeloupe had been evacuated and that one peasant had refused to leave, [he] knew [he] wanted to go talk to him and find out what kind of relationship towards death he had" (Cronin).  Herzog explores the deserted streets of the towns on the island.  The crew of three treks up to the caldera, where clouds of sulfurous steam and smoke shift drift like "harbingers of death" (Peucker), an example of the sublime Herzog seeks to conjure in his films.  Herzog converses in French with three different men he finds remaining on the island: one says he is waiting for death, and demonstrates his posture for doing so; another says he has stayed to look after the animals.  In the end, the volcano did not erupt, thus sparing the lives of those who had remained on the island, including Herzog and his crew.

Where the Green Ants Dream: Where the Green Ants Dream (German: "Wo die grünen Ameisen träumen" ) is a 1984 film by German film director Werner Herzog.  It was Herzog's first film in English.  Based partly on the "Milirrpum v Nabalco Pty Ltd" case and making use of professional actors as well as Aboriginal activists who were involved in the case, it was a mix of facts and fiction.  The ant mythology was claimed as Herzog's own, but some natives did consider the green ant as the totem animal that created the world and humans.  Wandjuk Marika noted that the ant dreaming belief existed in a clan that lived near Oenpelli in the Northern Territory.  The film is set in the Australian desert and is about a land feud between a mining company called Ayers (based on Nabalco) and the native Aborigines.  The Aborigines claim that an area the mining company wishes to work on is the place where green ants dream, and that disturbing them will destroy humanity.  The film was entered in the 1984 Cannes Film Festival.
