The fourth episode starts off with the two riding through Santa Cruz, Argentina. The plan is to cross over into Chile and then going up into the Andes. Ewan and Charley head through Argentina’s red rock landscape while a member of their team copes with altitude sickness. The duo are well and truly underway and the first signs of all are well is how well the Harleys hold up in challenging conditions. The roads alternate between unforgiving and pleasant and these e-bikes push through effortlessly. As they ride through Chilean Andes, the audience is shown a picturesque view of the beauty of the countryside, an experience which Boorman calls 'magical.'

Writing itself is 5,000 years old, and for most of that time words were written by hand using a variety of tools. The Romans were able to run an empire thanks to documents written on papyrus. Scroll books could be made quite cheaply and, as a result, ancient Rome had a thriving written culture. With the fall of the Roman Empire, papyrus became more difficult to obtain. Europeans were forced to turn to a much more expensive surface on which to write: Parchment. Medieval handwritten books could cost as much as a house, they also represent a limitation on literacy and scholarship.
No such limitations were felt in China, where paper had been invented in the second century. Paper was the foundation of Chinese culture and power, and for centuries how to make it was kept secret. When the secret was out, paper mills soon sprang up across central Asia. The result was an intellectual flourishing known as the Islamic Golden Age. Muslim scholars made discoveries in biology, geology, astronomy and mathematics. By contrast, Europe was an intellectual backwater.
That changed with Gutenberg’s development of movable type printing. The letters of the Latin alphabet have very simple block-like shapes, which made it relatively simple to turn them into type pieces. When printers tried to use movable type to print Arabic texts, they found themselves hampered by the cursive nature of Arabic writing. The success of movable type printing in Europe led to a thousand-fold increase in the availability of information, which produced an explosion of ideas that led directly to the European Scientific Revolution and the Industrial Revolution that followed.

We take it for granted, but every time we pick up a pen or type on the keyboard, we are employing the most powerful technology ever invented: the technology of writing. Explore how the invention of writing gave humanity a history. From hieroglyphs to emojis, the series is an exploration of the way in which the technology of writing has shaped the world we live in.
The invention of writing about 5,000 years ago made civilization itself possible, and every innovation of the modern world is based on the foundation of the written word. But how and where did writing begin, and who began it? In From Pictures to Words, the first of three films about the history of writing, we uncover the hidden links between all the diverse writing systems in use today and trace the origin of our own alphabet to a turquoise mine in the Sinai Desert and a man riding a donkey whose name was Khebded.

Ewan McGregor and Charley Boorman, after more than a decade since their last motorbike adventure around the world, will cover 13,000 miles over 100 days through 13 countries. Starting from the city of Ushuaia at the tip of South America, Ewan and Charley travel through the glorious and underexposed landscapes of South and Central America to Los Angeles in the United States in their most challenging expedition to date. In their journey they will use cutting-edge technology on the backs of their prototype electric Harley-Davidsons in order to contribute to the sustainability of the planet.
In the first episode, Ewan McGregor reunites with his best friend Charley Boorman to evaluate what's important in their lives, following a life-threatening accident of Charley.

A definitive account of Putin's power and how it changed the modern world. The series is an exploration of how Vladimir Putin brought his knowledge of spy-craft to bear on his leadership of Russia, how his personal experiences have influenced his politics and how modern Russia has been created through an acute sense of betrayal, pride and anger.
The first episode takes viewers on a journey into the mind of one of the 21st century's most influential leaders, offering a portrait of a politician who modelled himself on the Russian James Bond and whose presidency reads like a spy thriller. We will see how Putin escapes poverty by joining the KGB, his reinvention as a political fixer in the aftermath of the collapse of the Soviet Union and how he gets into position to take over from President Yeltsin.

Foo Fighters commemorate their 20th anniversary by documenting the eight-city recording odyssey that produced their latest, and eighth, studio album. Foo Fighters founder Dave Grohl directs the series, which taps into the musical heritage and cultural fabric of eight cities: Chicago, Austin, Nashville, Los Angeles, Seattle, New Orleans, Washington D.C. and New York. The band based themselves at a legendary recording studio integral to the unique history and character of each location. One song was recorded in each city, and every track features local legends. Even the lyrics were developed in an experimental, unprecedented way: Grohl held off on writing them until the last day of each session, letting himself be inspired by the experiences, interviews and personalities that became part of the process. Foo Fighters Sonic Highways is, in Grohl’s words, “a love letter to the history of American music.” Each episode delves into the identity of each city -- showing how each region shaped these musicians in their formative years and, in turn, how they impacted the cultural fabric of their hometowns. Every artist who appears in the show, regardless of genre or locale, started as an average kid with universal dreams of making music and making it big. Grohl made his feature film directorial debut in 2013 with the universally acclaimed Grammy-winning Sound City, a celebration of the human element in the creation and recording of music. Foo Fighters have won 11 Grammy Awards, including four for Best Rock Album, more than any other band. Premiering on the eve of Foo Fighters’ 20th anniversary, Foo Fighters Sonic Highways aims to “give back” to the next generation of young musicians. As guitarist and singer Buddy Guy, an interviewee from the Chicago blues scene, explains, “Everything comes from what’s come before.”
In the first episode, Dave Grohl and friends discuss the rise of the famous Chicago music scene from the roots blues of Muddy Waters and Buddy Guy to the Rock and roll of Cheap Trick.
