Sagan discusses comets and asteroids as planetary impactors, giving recent examples of the Tunguska event and a lunar impact described by Canterbury monks in 1178. It moves to a description of the environment of Venus, from the previous fantastic theories of people such as Immanuel Velikovsky to the information gained by the Venera landers and its implications for Earth's greenhouse effect. The Cosmos Update highlights the connection to global warming.

Helvetica is a feature-length independent film about typography, graphic design and global visual culture. It looks at the proliferation of one typeface (which celebrated its 50th birthday in 2007) as part of a larger conversation about the way type affects our lives. The film is an exploration of urban spaces in major cities and the type that inhabits them, and a fluid discussion with renowned designers about their work, the creative process, and the choices and aesthetics behind their use of type.
The film encompasses the worlds of design, advertising, psychology, and communication, and invites us to take a second look at the thousands of words we see every day.
Interviewees in Helvetica include some of the most illustrious and innovative names in the design world, including Erik Spiekermann, Matthew Carter, Massimo Vignelli, Wim Crouwel, Hermann Zapf, Neville Brody, Stefan Sagmeister, Michael Bierut, David Carson, Paula Scher, Jonathan Hoefler, Tobias Frere-Jones, Experimental Jetset, Michael C. Place, Norm, Alfred Hoffmann, Mike Parker, Bruno Steinert, Otmar Hoefer, Leslie Savan, Rick Poynor, and Lars Müller.

Eric C. Conn became a local celebrity and maybe even became heroic in the eyes of the people they were helping. He put up billboards all over the county and his parties were legendary. Conn took monthly vacations to exotic locations as a sex tourist and his 16 marriages were the talk of the town.
In the third episode, a new U.S. attorney begins working the case. Things take a dark turn when several of Conn's former clients share their experiences. Wanted by the FBI, chased by the authorities, the story soon spirals into a twisty-turny thriller. That’s no coincidence either, given Conn mentions numerous times that he likens himself to James Bond. James Bond with a dash of Robin Hood.

The State Hermitage Museum in St Petersburg is one of the largest and most visited museums in the world. Margy Kinmonth's film tells the story of its journey from imperial palace to state museum, investigating remarkable tales of dedication, devotion, ownership and ultimate sacrifice, showing how the collection came about, how it survived tumultuous revolutionary times and what makes the Hermitage unique today. Holding over three million objects and boasting more curators than any other museum, the Hermitage's story is Russia's history in microcosm and its art has lived to tell the tale

In the days of the Mayas, cenotes – deep, natural pits on the Yucatan peninsula - provided the only means of obtaining drinking water. But in the mythology of this advanced civilisation, these waterholes and caves were also the entrance to Xibalba – the underworld. All deceased were obliged to pass through Xibalba and wait there until they were called into heaven. It was a place in which one made sacrifices to the gods – objects of daily life, as well as bloody, human sacrifices. To this day, the relics of these acts are still in place preserved underwater for more than a thousand years. The entrance to the underworld begins at a dirty waterhole in the middle of the Mexican jungle overgrown and barely recognisable. But immediately after entry, a hall of breath-taking dimensions and beauty is revealed. As if they were sculptures, stalactites and stalagmites lend the underwater cave an almost sacred ambience. By now, one has succumbed to the fascination emanated by the world’s largest underwater cave system. We accompany four professional research divers to Yucatan – a team of specialists, able to squeeze their bodies through crevices and holes, barely larger than their bodies and who master dives that would push even the most experienced divers to their limits. With them, we penetrate worlds only a few people have ever ventured into. We encounter the remains of human victims, prehistoric fireplaces and primeval animal skeletons and undertake a dive, which takes us from the primeval forest to the open sea. We then enter Xibalba – the place of myths and the dead. In the days of the Mayas - a voyage of no return. Today, this is one of the greatest challenges one can face as a diver – the hidden world of the underwater caves of Yucatan – all filmed in 3D.

Richard Rudgley goes in search of evidence of the barbarians of the dark ages, people whose names have for 1500 years been bywords for mindless brutality. The real truth about the barbarians who marched across Europe during the Dark Ages is more shocking than what you may know. Where did they come from? Who are their descendants? Are any of their techniques and inventions still used? Richard discovers the secrets of forgotten empires, and of mighty clashes throughout Europe. The art, society and cultural legacy of the barbarians are shown to have shaped and moulded the destiny of Europe even more than the Roman Empire.
In the first part of the journey through the Dark Ages we will be tracing the legacies of the Huns, Vandals and Goths, to ask whether the 'dark ages' represent a resurfacing of much older tribal lines. Sites in Austria show how sophisticated pre-Roman communities had become with evidence of stunning craftsmanship and sophisticated farming techniques which defy the image of a mindless rabble we have come to accept without challenge.
