Watch Earth (2007) Online

The first film in the Disney nature series, Earth tells the remarkable story of three animal families and their amazing journey across the planet we all call home. earth combines rare action, unimaginable scale and impossible locations by capturing the most intimate moments of our planet's wildest and most elusive creatures. Directors Alastair Fothergill and Mark Linfield, the acclaimed creative team behind the Emmy Award(r)-winning "Planet Earth," combine forces again to bring this epic adventure to the big screen, beginning Earth Day 2009.

Over the course of a calendar year, Earth takes the viewer on a journey from the North Pole to the South, revealing how plants and animals respond to the power of the sun and the changing seasons. The film focuses on three particular species, the polar bear, African elephant and humpback whale.

In the high Arctic, as the darkness of winter gives way to the sun, a mother polar bear is shown emerging from her den with two new cubs. She needs food and must lead her cubs to her hunting ground on the sea ice before it begins to break up. By April, the sun never sets, and by August all the sea ice has melted. The mother and cubs have retreated to dry land, but a male polar bear is trapped at sea and must seek out land by swimming. He reaches an island with a walrus colony but is too exhausted to make a successful kill. He dies from injuries sustained in a walrus attack.

African elephants are filmed from the air as they negotiate a dust storm in the Kalahari Desert. June is the dry season and they must follow ancient paths passed down through generations to reach watering holes. A mother and calf are separated from the herd in the storm but manage to reach shelter. The matriarch leads the herd to a temporary watering hole, but they must share it with hungry lions. The lions are shown attacking a solitary elephant at night, when their superior vision gives them the upper hand. The herd times its arrival at the Okavango Delta to coincide with seasonal floodwaters which transform the desert into a lush water world.

A humpback whale mother and calf are filmed from the air and underwater at their breeding grounds in the shallow seas of the tropics. There is nothing here for the mother to eat, so she must guide her calf on a 4,000-mile (6,400 km) journey south to the rich feeding grounds near Antarctica, the longest migration of any marine mammal. En route, they negotiate dangerous seas where great white sharks are filmed breaching as they hunt sealions, and sailfish and dolphins combine to bait a shoal of small fish. By October they enter polar waters, and by December the Antarctic sun has melted the sea ice to form sheltered bays. Here, the whales are shown feeding on krill by trapping them in bubble nets.

The stories of these individual creatures are woven into the film alongside a great many additional scenes. The supporting cast of animals include mandarin ducklings filmed jumping from their tree hole nest, Arctic wolves hunting caribou, cheetah hunting Thomson's gazelle, birds of paradise displaying in the New Guinea rainforest and demoiselle cranes on their autumn migration across the Himalayas.

Time-lapse photography is used to show the blossoming of spring flowers, seasonal changes to deciduous forests, clouds sweeping up Himalayan valleys and the growth of jungle spores and fungi.

The narration makes reference to environmental changes throughout the film, and uses the three featured species to illustrate particular threats to the planet's wildlife. In the Arctic, rising temperatures are causing a greater area of sea ice to melt and threatening the polar bear with extinction as early as 2030. Global warming is also disrupting the planet's weather systems and making seasonal rainfall patterns less predictable. This poses a threat to creatures like elephants, which must travel greater distances to reach water. Rising ocean temperatures have started to kill the plankton on which humpback whales and most other sea life depend. However, the film also ends with the message that "it's not too late to make a difference".

Earth was produced by Alix Tidmarsh of BBC Worldwide and Sophokles Tasioulis of Greenlight Media. Following Deep Blue, it is the second film of a five-picture deal between the two companies.

The process of bringing Planet Earth and Earth to the screen took over 5 years. With a combined budget of USD47 million, USD15 million of which was earmarked for the film, it represented the most expensive production in the history of documentary filmmaking.

Principal photography began in 2004 and was completed in 2006.

Earth received its global premiere at Spain's San Sebastian International Film Festival in September 2007. It was released across Europe in the fourth quarter of 2007 to much success. It grossed over USD30 million at the German box office, became one of the three highest-grossing films of the year in France and had the best opening of any natural history documentary in Spain. By contrast, in the UK Earth debuted on just 14 screens and went on to gross less than GBP75,000.

In January 2008, the Japanese version of Earth, narrated by actor Ken Watanabe, knocked Hollywood blockbuster I Am Legend off the top of the box office despite opening on half the number of screens. It went on to gross more than 2 billion yen (USD18.5 million), making it the most successful documentary there of the last 10 years.

In April 2008, it was announced that Earth would be the first feature distributed by the newly-formed Disneynature, a subsidiary of the Disney Company specialising in natural history documentaries. The film will get a US theatrical release in 2009, though its narration is getting divided theories of James Earl Jones recording a new narration or the US release will retain Patrick Stewart's original narration. Disneynature will also distribute the film in Latin American territories.
