Wexler’s exploration of the overworking of crew in the film industry dovetails nicely with the point that the American worker is working longer hours than ever with no pay change. He confronts the union leadership and OSHA and finds himself confronted by polite stonewalling. The movie drives home well the necessity of sleep, and carries an implicit but low-key indictment of profits over people(née Capitalism). It also has a bit of sadness over the decline of union people power from the veteran cinematographer. In the 60s he worked 8 hour days. No more.
