During 1964-1969 both sides now plan to put a man on the Moon - while the Soviets struggle, the Americans pull ahead in the space race with Project Gemini, but then suffer a disaster with the Apollo 1 fire. The Soviet space programme suffers its own blows: Sergei Korolev dies when his heart fails during an operation, Soyuz 1 crashes and kills cosmonaut Vladimir Komarov, and their planned moon rocket, the N-1 rocket, fails to successfully launch. In America, von Braun has difficulties with the Saturn V, but they are overcome, and the rocket successfully launches the first manned lunar mission, Apollo 8, and the first manned lunar landing, Apollo 11.

Invertebrates don't always operate alone. True society was the last feature to evolve in invertebrates, as recently as the time of Tyrannosaurus. In the last programme see the tensions below the surface in some of the great social structures built by insects, and witness the carnage when an ant colony and a termite colony wage war.

Every summer in the seas off Alaska humpback whales, sea lions and killer whales depend on an explosion of plant life, the plankton bloom. It transforms these seas into the richest on Earth. But will these animals survive to enjoy the great feast? The summer sun sparks the growth of phytoplankton, microscopic floating plants which can bloom in such vast numbers that they eclipse even the Amazon rainforest in sheer abundance of plant life. Remarkably, it is these minute plants that are the basis of all life here. But both whales and sea lions have obstacles to overcome before they can enjoy the feast. Humpback whales migrate 3,000 miles from Hawaii, and during their 3 month voyage lose a third of their body weight. In a heart-rending scene a mother sea lion loses her pup in a violent summer storm, while another dramatic sequence shows a group of killer whales working together to kill a huge male sea lion.
In late summer the plankton bloom is at its height. Vast shoals of herring gather to feed on it, diving birds round the fish up into a bait ball and then a humpback whale roars in to scoop up the entire ball of herring in one huge mouthful. When a dozen whales work together they employ the ultimate method of co-operative fishing - bubble net feeding. One whale blows a ring of bubbles to engulf the fish and then they charge in as one. Filmed from the surface, underwater and, for the first time, from the air, we reveal how these giant hunters can catch a tonne of fish every day.

Survival of the fittest: Raw competition? Intense cooperation? Both are essential. Interactions between and within species are among the most powerful evolutionary forces on Earth, and understanding them may be a key to our own survival.

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.
