Dudley Riggs transformed the Twin Cities theatre scene in 1958 when his Brave New Workshop introduced audiences to “instant theatre.” Today, the BNW is the longest running improv comedy theater in America and has helped launch the careers of some of Minnesota’s funniest entertainers including Louie Anderson, Liz Winstead and Al Franken. Riggs discusses how he conceived of this new type of theatre and his memoir, “Flying Funning: My Life without a Net.”
