Millions know their voices, but no one knows their names. In his compelling film, award-winning director Morgan Neville shines a spotlight on the untold true story of the backup singers behind some of the greatest musical legends of the 21st century.
Triumphant and heartbreaking in equal measure, the documentary is both a tribute to the unsung voices who brought shape and style to popular music and a reflection on the conflicts, sacrifices and rewards of a career spent harmonizing with others. These gifted artists span a range of styles, genres and eras of popular music, but each has a uniquely fascinating and personal story to share of life spent in the shadows of superstardom.
Along with rare archival footage and a peerless soundtrack, 20 Feet from Stardom boasts intimate interviews with Bruce Springsteen, Stevie Wonder, Mick Jagger and Sting to name just a few. However, these world-famous figures take a backseat to the diverse array of backup singers whose lives and stories take center stage in the film.

In this programme, Mary descends into the city streets to discover the dirt, crime, sex and slum conditions in the world's first high-rise city. This Rome is not the marble Rome we know, but a vast, messy metropolis with little urban planning, where most Romans lived in high-rise apartment blocks with little space, light, or even sanitation. Forced outdoors into the city streets, she reveals where they went to hang out, get drunk, have sex and get clean. She looks at the Forum as a place of gamblers, dentists and thieves, and she explores the lustiness of Roman bar life and jokes. Finally, exploring law and order from the bottom up, Mary examines how this city really worked. She meets Ancarenus Nothus, an apartment dweller who lived in fear of the rent collector; Notorious Primus, who wrote about his three great pleasures in life - baths, wine and sex; and Unlucky Doris, a seven-year-old girl killed in one of Rome's many fires.

We think of comets as beautiful glowing balls of light streaking across our skies with their long sweeping tails, yet comets are so much more than just a cosmic firework display. Comets have a uniquely important place in modern science. As time machines from the early universe, they could hold the key to unlock the secrets of the cosmos. Comets could even be the origin of life itself. We follow the incredible odyssey of a comet as it sails through the solar system, watching it's every move as it evolves from a dormant chunk of ice and rock into a tumbling, violently active nucleus engulfed in a gaseous haze. What we learn is a revelation; comets are even more mysterious and fascinating than we had ever imagined.

Push the limits of your imagination as astronomers attempt to grasp the mind-boggling extremes of size, distance and speed within our universe by bringing them down to earth. In this episode, our cast uses awesome analogies to bring the biggest objects, farthest distances and fastest speeds down to earth. To truly understand the scale of the cosmos, we jump behind the wheel of monster trucks, scale the Golden Gate Bridge, and race across the desert in a rocket-powered car.
