Cane Toads: The Conquest, a 2010 documentary film by Mark Lewis, tracks the inexorable decades long march of the invasive cane toad across Australia, a "sequel of sorts" to his 1988 cult classic, Cane Toads: An Unnatural History. It is described as an "irreverent" blend of "history, nature footage, re-enactments and colorful testimony," documenting what is widely considered to be one of Australia's biggest environmental disasters through its effect on people. It was filmed in 3D.

Plot

The film combines old newsreels, nature footage featuring cane toads in action, re-enactments of toad-related events, and the first-hand accounts of people's interactions with the toads. The story begins with the toads in full form 15 million years ago, and fast-forwards to the 1935 introduction of 102 cane toads to Australia in an ill-conceived attempt to take on the cane beetle devastating sugarcane crops. The toads' proliferation got out of hand, and they became a seriously invasive species, marching across Australia, capturing huge swaths of territory over the decades. Various characters, including scientists, farmers, and everyday people, provide testimony about the creatures.
