In this curious series, the minds behind history's most iconic toy franchises will discuss the rise (and sometimes fall) of their billion-dollar creations.
In 1977, after being rejected by Mattel and Hasbro, Lucasfilm signed with Kenner Products to have toys produced for their sci-fi film Star Wars. This was a huge gamble, as Kenner was a small toy company at the time and the negotiation process started late due to George Lucas' secrecy over the ship designs. Since then, toy sales of the Star Wars franchise have totaled to US$14 billion worldwide.

The key to understanding the universe seems to be understanding its smallest components. But the quantum realm bears little resemblance to the universe we know. Image a particle that can be many places at the same time and communicate changes instantly across vast distances, even to the other side of the Universe. Shrinking down billions of times, into the realm of atoms and sub-atomic particles, takes us into a bizarre world of paradoxes and multiverses. Explore with us quantum physics and the potential applications in computer science.

We routinely talk about healthy food and clean water, but how often do we spare a thought for what enters our lungs? The World Health Organization calls air pollution the silent killer. Air pollution is proven to shorten our lifetimes and it hits the vulnerable - children, the sick and the elderly - hardest of all.
Prince William, Sir David Attenborough and astronaut Naoko Yamazaki hear the personal stories of people who are directly affected by air pollution and show us incredible solutions.

Lesotho's Maseru Central Correctional Institute in Southern Africa holds the country's most dangerous and disturbed criminals. Shockingly almost half the inmates are doing time for rape. The culture of sexual violence in Lesotho has deep roots in society. Women are taken as secondary citizens in their culture. And sexual aggression continues inside the prison.
In this episode, Raphael Rowe will spend a week locked up in this African prison surrounded by sex offenders.

Long ago, two species of human beings coexisted on Earth until competition drove one of them to extinction. This program, set in the southwest of France 35,000 years ago, reconstructs the life in the Neanderthal world at the time Cro-Magnons first entered the scene. All aspects of Neanderthal clan life are examined, including tool- and weapon-making, hunting and gathering, health and healing, childbirth, rituals, and making fire. Footage of skeletal remains and the scholarly research of eminent paleontologist Chris Stringer and Oxford University's Paul Pettitt support the documentary.

In 2014, the International Space Station had to move three times to avoid lethal chunks of space debris and there is an increasing problem of satellites mysteriously breaking down. With first-hand accounts from astronauts and experts, know the scale of the problem of space junk. Our planet is surrounded by hundreds of millions of pieces of junk moving at 17,000 miles per hour. Now the US government is investing a billion dollars to track them, and companies around the world are developing ways to clear up their mess - from robot arms to nets and harpoons. Learn the science behind the hit film Gravity and discovers the reality is far more worrying than the Hollywood fiction.
