Next to the Colosseum there’s Monti (2008)

There's an area of Rome, near the Colosseum, called Monti. Given famous Italian director Mario Monicelli, though born in Tuscany, has lived there for years and wanted to show the world age has yet to cripple him (he was 93 when he made this), he filmed hours of footage which were eventually turned into a 22-minute documentary that was screened Out of Competition at the 2008 Venice Film Festival.
