For 750 years, the local colosseum was the only place to go if you were looking for some action. What began as human sacrifice during funeral rites for wealthy families resulted in a violent, bloody battle staged in front of 50,000 fans. Gladiators were slaves, but the archaeological remains at Pompeii and the Roman Colosseum reveal that they were held in the same esteem as modern day sports stars. Gladiators explains how this "sport" was used as a tool of political power and how the Gladiators rose up and waged war against their owners. Two versions are available: presenter-free, and presenter-led, with Terry Jones of Monty Python fame.

Renaissance artist Leonardo da Vinci may be best known for his paintings, but engineers consider him just as much a genius for the machines he designed that were years ahead of their time. This film narrated by Richard Denton documents the attempts of modern experts to build some of da Vinci's designs, including a massive crossbow with arms 70 feet across and a glider that he imagined more than four centuries before humans first took flight.
