In the Pit (2006)

Several work crews battle to give a traffic-bogged, over-smogged Mexico City freeway an upper level in this earthy documentary from Juan Carlos Rulfo. Showcasing the jokes, curses and philosophizing of a little-seen underclass of the upper deck, the film fashions a tribute to those who keep “progress” moving, one brick and mortar at a time. His 1997 homage to his father, Juan, I Forgot, I Don't Remember, garnered praise in festivals around the world.
