Charna Halpern Called the "Comedy Mother" by former student Adam McKay, director of Anchorman and Talladega Nights, Halpern has nurtured the careers of countless comedians as the manager of I.O. (formerly ImprovOlympic), which she founded in 1981. Halpern and the late Del Close revolutionized improvisation in 1983 when they developed I.O.'s signature long-form technique. Her latest book, Art by Committee, which came out this summer, details advanced improv techniques.
