John Pierson's essential 1995 tome, "Spike, Mike, Slackers and Dykes: A Guided Tour Across a Decade of American Independent Cinema," features interstitial Q&As with a 24-year-old Kevin Smith designated as the book's hesitant "generational spokesman." At one point, he strikes a prescient tone: "Note to myself," he says. "If I ever in a future life get a new start as a first-time filmmaker, give me lines to be funny with." With Smith's lack of screenwriting credit on "Cop Out," that new life has ostensibly begun, but the essential Smith contradiction remains agreeably intact. In another 15 years, who knows?
