The Private Life of Plants: Travelling

   1994    Nature
Sir David Attenborough reveals plants as they have never been seen before - on the move and dangerously devious. About the major problems of life - growing, finding food, reproduction - and the varied ways plants have evolved to solve it. Filmed from the plant's point of view, using computer animations, fibre-optics and unique time-lapse photography. The first episode looks at how plants are able to move". The bramble is an aggressive example: it advances forcefully from side to side and, once settled on its course, there is little that can stand in its way. An altogether faster species is the birdcage plant, which inhabits Californian sand dunes. When its location becomes exposed, it shifts at great speed to another one with the assistance of wind — and it is this that allows many forms of vegetation to distribute their seeds. While not strictly a plant, the spores of fungi are also spread in a similar fashion. One of the most successful (and intricate) flowers to use the wind is the dandelion, whose seeds travel with the aid of 'parachutes'. They are needed to travel miles away from their parents, who are too densely packed to allow any new arrivals. Trees have the advantage of height to send their seeds further, and the cottonwood is shown as a specialist in this regard. The humidity of the tropical rainforest creates transportation problems, and the liana-species Alsomitra macrocarpa is one plant whose seeds are aerodynamic 'gliders'. Some, such as those of the sycamore, take the form of 'helicopters', while others, such as the squirting cucumber release their seeds by 'exploding'. Water is also a widely used method of propulsion. The tropical sea bean Entada gigas has one of the biggest fruits of all plants and is dispersed by water streams. However, most plants use living couriers, whether they be dogs, humans and other primates, ants or birds, etc., and to that end, they use colour and smell to signify when they are ripe for picking.

Destination Titan

   2011    Technology
It's a voyage of exploration like no other - to Titan, Saturn's largest moon and thought to resemble our own early Earth. For a small team of British scientists this would be the culmination of a lifetime's endeavour - the flight alone, some 2 billion miles, would take a full seven years. This is the story of the space probe they built, the sacrifices they made and their hopes for the landing. Would their ambitions survive the descent into the unknown on Titan's surface?

Colours Of Earth

   2015    Science
In this episode, Helen seeks out the colours that turned planet Earth multicoloured. To investigate the essence of sunlight Helen travels to California to visit the largest solar telescope in the world. She discovers how the most vivid blue is formed from sulfur atoms deep within the Earth's crust and why the presence of red ochre is a key sign of life. In gold, she discovers why this most precious of metals shouldn't even exist on the surface of the planet and in white, Helen travels to one of the hottest places on Earth to explore the role salt and water played in shaping planet Earth.

Magician: The Astonishing Life and Work of Orson Welles

   2014    Culture
This documentary looks at the remarkable genius of Orson Welles on his centenary - the enigma of his career as a Hollywood star, a Hollywood director (for some a Hollywood failure), and a crucially important independent filmmaker. Orson Welles's life was magical: a musical prodigy at age 10, a director of Shakespeare at 14, a painter at 16, a star of stage and radio at 20, romances with some of the most beautiful women in the world, including Rita Hayworth. His work was similarly extraordinary, most notably Citizen Kane, (considered by many to be the most important movie ever made), created by Welles when he was only 25. In the years following Citizen Kane, Welles's career continued to change as he made film after film (some never finished, many dismissed) and acted in other projects often to earn money in order to keep making his own films. Magician features scenes from almost every existing Welles film, from Hearts of Age, (which he made in a day when he was only 18 years old) to rarely-seen clips from his final unfinished works like The Other Side of the Dream, The Deep, and Don Quixote, as well as his television and commercial work.
