Earth: One Amazing Day

Tells the story of life on earth in the course of one single day, narrated by Robert Redford and made by BBC Earth Films. This film features stunning visuals and scored a 100 per cent positive rating on the critical aggregator website Rotten Tomatoes. The family feature took three years to make, was filmed over 142 filming days in 22 countries and features 38 different species. It takes viewers up close and personal with a cast of unforgettable characters - a baby zebra desperate to cross a swollen river, a penguin who heroically undertakes a death-defying daily commute to feed his family, a family of sperm whales who like to snooze vertically, and a sloth on the hunt for love. 'As a storyteller and film-maker I often look to nature for sources of inspiration', said Robert Redford, narrator. 'In Earth: One Amazing Day, BBC Earth Films captured the natural world and its inhabitants using the perfect combination of storytelling and cutting-edge technology. The scenes and images are as inspirational as they are beautiful, and I was honoured to be a part of the film'. Told with humour, intimacy, emotion and a jaw-dropping sense of cinematic splendour, this film is a colourful, ultra-vivid family friendly adventure that spectacularly highlights how every day the natural world is filled with more unseen dramas and wonders than can possibly be imagined - until now.

Mammals dominate the planet. They do it through having warm blood and by the care they lavish on their young. Weeks of filming in the bitter Antarctic winter reveal how a mother Weddell seal wears her teeth down keeping open a hole in the ice so she can catch fish for her pup. A powered hot air balloon produces stunning images of millions of migrating bats as they converge on fruiting trees in Zambia, and slow-motion cameras reveal how a mother rufous sengi exhausts a chasing lizard. A gyroscopically stabilised camera moves alongside migrating caribou, and a diving team swim among the planet's biggest fight as male humpback whales battle for a female.
