A tribute to documentary filmmaker Frederick Wiseman

Acclaimed filmmaker Frederick Wiseman, who died in February at age 96, revolutionized the art of documentaries with such films as "Titicut Follies," "High School," and "Hospital." In an interview with "Sunday Morning" recorded last year, the pioneering Wiseman talked with David Pogue about his unusual production methods aimed at capturing life, in films as funny, sad, and tragic as any fiction film.
