James Cameron has called Donald Trump a “madman” and criticised the Republican presidential candidate over his denial of climate change, according to the Associated Press.
In a statement, Cameron said: “We made this film to show the reality of climate change – how it’s directly affecting millions of people each day.
Hillary Clinton makes a late cameo, but the starring role is saved for Trump himself, who is shown at various rallies ridiculing the idea of climate change.
The film features well-known figures including Jack Black, Don Cheadle and the Pope, who is shown describing a planet teetering on the brink of “suicide”.
