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. This cinematic eye into the daily lives of construction workers building the second deck of Mexico City’s “Periferico” Freeway was nominated for the 2005 Sundance World Cinema Competition; Best Documentary Feature, Miami International Film Festival.
