What if aliens landed on Earth? Much of science fiction explores the moment of first contact – what will people do when the aliens land? From H. G. Wells’ pioneering The War of the Worlds to Independence Day, Men in Black, and District 9, Invasion deals with our fears of alien invasions of earth. David Tennant explains the appeal of Doctor Who’s Daleks and Cybermen while John Carpenter and Chris Carter explore the rich appeal of the paranoia fuelled by hidden aliens with The Thing and The X-Files. It also asks, what if the monsters were our own creation? With the aid of rarely seen animation tests, Phil Tippett takes us behind the scenes in the creation of the dinosaurs of Jurassic Park. But not all invasions are hostile. Peter Coyote and Richard Dreyfuss discuss the creation of Spielberg’s spellbinding classics E.T. the Extra-Terrestrial and Close Encounters of the Third Kind. There is more than one kind of invasion.

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.

How does light escape from the sun? We take a journey from the center of the sun, following the path of light. We witness its fiery birth from in the core, its 430,000 mile battle against gravity and magnetism, and its escape from the solar surface.

The first second of the Universe, the creation of everything when space, time, matter and energy burst into existence. It is the most important second in history, which seals the Universe's fate and defines everything that comes after - including us.

'Deliver Us from Drought' - Over the past years, Texas has experienced the worst drought in its recorded history. 97% of the scientific community agrees that human activity has contributed to extreme weather patterns around the world. But many Texans--legislators, community leaders and citizens--don't attribute their drought to humans, and have taken few if any initiatives to limit the state's CO2 emissions, currently the highest in the country. "The Resource Curse" - As humanity's appetite for energy grows exponentially, the extraction industry scrambles to the most remote regions on Earth. In the undeveloped Melanesian country of Papua New Guinea, America's Exxon Mobil has staked its claim to a $19 billion liquid natural-gas project. While some see Exxon's mammoth presence as the catalyst that will usher the underdeveloped country into the 21st Century, others predict the initiative could plunge its people into civil war.
