The Violent Universe

It has been said that 10,000 years from now only one name will still be remembered, that of Neil Armstrong.

He tracks down the people who knew Armstrong, from his closest childhood friend to fellow astronauts and Houston technicians, and even the barber who sold his hair, in a wry and sideways look at the reluctant hero of the greatest event of the 20th century.

THE GREAT AUSTRALIAN FLY looks at how a national nuisance has shaped Australia and its people, confounding our scientists, influencing our lifestyle and defining the way we speak. But is its value misunderstood? The one-hour documentary explores how this much-maligned spoiler of the Australian summer is in fact a crime solver, healer, pollinator and street sweeper. We'd miss them if they were gone, yet we put huge amounts of energy into wiping them out. Is it time to call a truce? Directed by Tosca Looby and produced by Sally Ingleton, the amusing and intriguing film pays homage to a much-maligned invertebrate and the influence it has had on our world.

The 1960s was an extraordinary time for the United States. Unburdened by post-war reparations, Americans were preoccupied with other developments like NASA, the game-changing space programme that put Neil Armstrong on the moon. Yet it was astronauts like Eugene Cernan who paved the uneven, perilous path to lunar exploration. A test pilot who lived to court danger, he was recruited along with 14 other men in a secretive process that saw them become the closest of friends and adversaries. In this intensely competitive environment, Cernan was one of only three men who was sent twice to the moon, with his second trip also being NASA’s final lunar mission. As he looks back at what he loved and lost during the eight years in Houston, an incomparably eventful life emerges into view. Director Mark Craig crafts a quietly epic biography that combines the rare insight of the surviving former astronauts with archival footage and otherworldly moonscapes.
