Robert Altman's life and career contained multitudes. This father of American independent cinema left an indelible mark, not merely on the evolution of his art form, but also on the western zeitgeist. With its use of rare interviews, representative film clips, archival images, and musings from his family and most recognizable collaborators, Altman is a dynamic and heartfelt mediation on an artist whose expression, passion and appetite knew few bounds.

Meet Nikola Tesla, the genius engineer and tireless inventor whose technology revolutionized the electrical age of the 20th century. Although eclipsed in fame by Edison and Marconi, it was Tesla's vision that paved the way for today's wireless world. His fertile but undisciplined imagination was the source of his genius but also his downfall, as the image of Tesla as a mad scientist came to overshadow his reputation as a brilliant innovator.

In 1910, the Pennsylvania Railroad successfully accomplished the enormous engineering feat of building tunnels under New York City's Hudson and East Rivers, connecting the railroad to New York and New England, knitting together the entire eastern half of the United States. The tunnels terminated in what was one of the greatest architectural achievements of its time, Pennsylvania Station. Penn Station covered nearly eight acres, extended two city blocks, and housed one of the largest public spaces in the world. But just 53 years after the station’s opening, the monumental building that was supposed to last forever, to herald and represent the American Empire, was slated to be destroyed.

By the time he died in 1931, Thomas Alva Edison was one of the most famous men in the world. The holder of more patents than any other inventor in history, Edison had achieved glory as the genius behind such revolutionary inventions as sound recording, motion pictures, and electric light. Born on the threshold of America's burgeoning industrial empire, Edison's curiosity led him to its cutting edge. With just three months of formal schooling, he took on one seemingly impossible technical challenge after another, and through intuition, persistence, and a unique team approach to innovation, invariably solved it. Driven and intensely competitive, Edison was often neglectful in his private life and could be ruthless in business. Challenged by competition in the industry he'd founded, Edison launched an ugly propaganda campaign against his rivals, and used his credibility as an electrical expert to help ensure that high-voltage electrocution became a form of capital punishment.
