Sir David Attenborough chooses his favorite recordings from the natural world --from the song of the largest lemur to the song of the humpback whale to the song of the lyrebird-- that have revolutionized our understanding of song. The science of song had been transformed by Charles Darwin’s theory of sexual selection: singing is dangerous as it reveals the singer’s location to predators, but it also offers the male a huge reward, the chance to attract a female and pass on genes to the next generation. Today, new science in the field of birdsong is transforming those long-held ideas.
Scientists are discovering that, in fact, in the majority of all songbird species, females sing - and it is only now they are being properly heard. Through this revelation and others, we can understand that animal songs are marvellous examples of the spectacular survival strategies that species have developed.

In just one generation, our ability to search for planets beyond our solar system has transformed. With modern techniques and telescopes, planetary scientists have found thousands of exoplanets in our universe, and many of them have the perfect conditions for life. Are we about to find Earth’s twin?

This is the story of two of the biggest scientific breakthroughs of the 21st century, told by the incredible scientists who made them happen. The first is LIGO’s measurement of gravitational waves coming from a black hole merger, and the second, the Event Horizon Telescope’s image of a black hole.

The film tells the story of the ill-fated Nazi Land Speed record attempts. This is a story of engineering excellence, Grand Prix racing, Nazi propaganda, celebrity, and an intense rivalry which would leave a speed record unbroken for 79 years and one of Nazi Germany's best racing drivers dead. During the rise of the Third Reich two German car manufacturers were ordered to build the most high performance vehicles the world had ever seen. What followed was a rivalry that would reap Grand Prix victories, international domination that was a propaganda coup, and provide world fame to its drivers who risked their lives smashing speed records that would stand for 79 years. All under the direct orders of the Fuhrer himself.
Bugatti and Alfa Romeo dominated racing before 1934. But the years from 1934 to 1939 were six tumultuous years in which Grand Prix racing was dominated by the German Auto Union, the arranged marriage of Audi, Horch, Wanderer, and DKW, and Mercedes-Benz teams and provided a spectacle of speed, sound and fury never previously attained and never since matched. There are few periods of racing that have excited as much interest, event attendance and sophistication of equipment as the era of the Silver Cars. They were so far ahead of their time that many of their accomplishments were not duplicated until Mercedes went racing again in the early 1950s. There is also something about men who faced the challenges of staying in a cockpit of a highly sophisticated machine capable of 200 mph with no safety systems. They were giants and among them were Italian Tazio Nuvolari and two greatest German pilots of the thirties, Rudolf Caracciola of Mercedes and Auto Union's Bernd Rosemeyer who duelled with faster, more innovative and sleeker machines, developed in wind tunnels.
This special documentary charts the rise of Nazi Germany's dominate 'Silver Arrow' Grand Prix and Speed Record cars of the 1930's. Leading motor racing and World War 2 experts James Holland, Richard Williams, Eberhard Reuss and Chris Routledge tell the story of the Nazi funded Auto Union and Mercedes Benz 'National Racing Cars'. Hitler's Supercars interweaves the rise of the Third Reich with the racing exploits it funded and what propaganda messages these racing cars where sending.

This rockumentary-style presidential portrait shows how Jimmy Carter reinvigorated a post-Watergate America-with the music of the counterculture, including the Allman Brothers, Bob Dylan, Willie Nelson, and Jimmy Buffett. Low on campaign funds and lacking in name recognition, Carter relied on support from these artists to give him a crucial boost in the Democratic primaries. Once Carter was elected, the musicians became frequent guests in the White House.

In 1971, after being rejected by Hollywood, Bruce Lee returned to his parents' homeland, Hong Kong. Over the next two years, he'd complete four iconic films that would define his legacy, a legacy cut short when he died, stunningly, in the summer of 1973. He was 32 years old. Directed by Bao Nguyen, 'Be Water' is a gripping, fascinating, intimate look at not just those final, defining years of Lee's life, but the complex, often difficult, and seismic journey that led to Lee's ultimate emergence as a singular icon in the histories of film, martial arts, and even the connection between the eastern and western worlds.
The film chronicles Lee's earliest days, as the son of a Chinese opera star born while his father was on tour in San Francisco, and then raised in Hong Kong over what became an at times troubled childhood. Sent to live in America at the age of 18, he began teaching Kung Fu in Seattle, and established a following that included his future wife, Linda. His ambition ever rising, Lee eventually made his way to Los Angeles, where he strove to break into American film and television. There, despite some success as a fight choreographer and actor, it was clear Hollywood wasn't ready for an Asian leading man - and so he returned to Hong Kong to make the films that would in fact make him a legend, his international star skyrocketing just as his life was cut short.
'Be Water' is told by the family, friends, and collaborators who knew Bruce Lee best, with an extraordinary trove of archive film providing an evocative, immersive visual tapestry that captures Lee's charisma, his passion, his philosophy, and the eternal beauty and wonder of his art.
