“Lit Up.”

Upton Sinclair: novelist, muckraker, socialist, utopian, pamphleteer, film producer, candidate, homeopath, fad dieter.Illustration by Edward Sorel A hundred years ago, Upton Sinclair, the muckraker and socialist, brought out “The Jungle,” a sensationally grim exposé of the noisome squalors and dangers of the meatpacking industry.

In 1937, Warner Bros. departed from its usual fare of jittery urban dramas and emotionally saturated women’s pictures. In a burst of ambition, it mounted a historical spectacle set in late-nineteenth-century Paris, “The Life of Emile Zola,” starring Paul Muni. “Zola” is meant to be a stirring man-of-conscience movie: after early struggles, followed by huge success, the writer, in self-satisfied middle age, gets drawn, with increasing fury, into the Dreyfus affair.

I loved Emily Nussbaum’s negative review of Aaron Sorkin’s new HBO series, “The Newsroom,” which had its première last Sunday night, but I also enjoyed the show—certainly more than she did—and, afterwards, I felt a kind of moviegoer’s chagrin. Movie audiences get very little dialogue this snappy; they get very little dialogue at all.
