This Criterion Collection release includes important extras, like a 1973 episode of French show, "Morceaux de bravoure," in which Tati speaks about his overall working methods. Also impressive is his daughter's full-length documentary, "In the Footsteps of Monsieur Hulot" (1989), which collects ample archival footage of Tati and his friend, professor A. Sauvy, discussing each film's invention. Here, Tati said of Trafic that he was inspired to make a film that would make people smile after noticing so many frowns on the Paris highways. Road rage assuaged by cinema is a truly Modern gesture. --Trinie Dalton
