A Finalist for the 2017 George Freedley Memorial Award "With Saturday Night Live looming ever larger in the pop culture landscape, it's time for a history of improv comedy. Wasson delivers, moving nimbly from improv's origins in 1950s Chicago to movies like Caddyshack and TV shows like The Colbert Report." —Entertainment Weekly "A compelling, absolutely unputdownable story . . . And, in case you're wondering, yes, the book is funny. In places, very funny. A remarkable story, magnificently told." —BooklistFrom the best-selling author of Fosse, a sweeping yet intimate—and often hilarious—history of a uniquely American art form that has never been more popular. At the height of the McCarthy era, an experimental theater troupe set up shop in a bar near the University of Chicago. Via word-of-mouth, astonished crowds packed the ad-hoc venue to see its unscripted, interactive, consciousness-raising style. From this unlikely seed grew the Second City, the massively influential comedy theater troupe, and its offshoots—the Groundlings, Upright Citizens Brigade, SNL, and a slew of others. Sam Wasson charts the meteoric rise of improv in this richly reported, scene-driven narrative that, like its subject, moves fast and digs deep. He shows us the chance meeting at a train station between Mike Nichols and Elaine May. We hang out at the after-hours bar Dan Aykroyd opened so that friends like John Belushi, Bill Murray, and Gilda Radner would always have a home. We go behind the scenes of landmark entertainments from The Graduate to Caddyshack, The Forty-Year Old Virgin to The Colbert Report. Along the way, we commune with a host of pioneers—Mike Nichols and Harold Ramis, Dustin Hoffman, Chevy Chase, Steve Carell, Amy Poehler, Alan Arkin, Tina Fey, Judd Apatow, and many more. With signature verve and nuance, Wasson shows why improv deserves to be considered the great American art form of the last half-century—and the most influential one today.
