The dome that crowns Florence's great cathedral of Santa Maria del Fiore, the Duomo, is a masterpiece of Renaissance ingenuity and an enduring source of mystery. Still the largest masonry dome on earth, it is taller than the Statue of Liberty and weighs as much as an average cruise ship. Historians and engineers have long debated how its architect, Filippo Brunelleschi, kept the dome perfectly aligned and symmetrical as the sides rose and converged toward the center." More than four million bricks could collapse at any moment -- and we still don't understand how Brunelleschi prevented it. To test the latest theories, a team of U.S. bricklayers will help build an experimental "mini-Duomo" using period tools and techniques.

It tells the story of FIFA World Cup of 1950, highlighting (but also showing other nations) the path of the two teams who played the final match: Uruguay and Brazil. The high quality of the footage is amazing, the text is smart and humorous, the music has been very well chosen in order to represent both the emotions involved in each moment and the contrast between the calmness of Uruguayan preparation and the crowded days of Brazilian team." The whole story shows not only one side. While Uruguayan team acquired confidence after an initial mistrust, Brazil was by far the best team in the competition but was heavily influenced by the environment in Brazilian society, the influence of politics and the pressure of the fans. While Uruguay overcame heroically all the constraints and, led by Obdulio Varela, won a title that few people believed, Brazilians got shocked because they considered themselves champions even before the final match, and their players became stigmatized until nowadays, not being celebrated as the fantastic team they were.
