Charna Halpern: Improv Comedy at Chicago's iO Theater
Everyone who works in television and movie comedy knows Charna Halpern. She’s trained thousands of actors, writers, and producers at her Chicago theater, founded in 1981, called the iO theater. In this episode, Charna tells personal and funny stories about actors from Chris Farley and Neil Flynn to Tina Fey and Amy Poehler. Along with actor and director Del Close, Charna invented modern improvisational theater in the 1980s. The art form known as long form improvisation—a 20 or 30-minute fully improvised one-act play—was developed at the iO theater, and is still found on their stage at seven nights a week at 1501 N. Kingsbury Street in Chicago.
Charna is one of the best-known and best-loved people in comedy because she developed a system for training actors how to improvise together. Her training takes a full year and it’s so effective that TV producers, like Lorne Michaels, regularly visit iO theater to audition the actors who’ve graduated from the program. Sometimes on Saturday Night Live, every actor was once at the iO theater.
Charna created a family, a community, that she lovingly calls “my people.” Here are just a few of the famous actors and writers who we talk about in this episode (in order of mention): Lorne Michaels; Cecily Strong; Tina Fey; Amy Poehler; Mike Myers; Vanessa Bayer; Adam McKay; Brian Stack; Stephen Colbert; David Koechner; Rachel Dratch; Chris Farley; Sarah Silverman; Stephanie Ware; Neil Flynn; Larry David; Seth Myers; John Lutz; Matt Walsh; Tim Meadows. She even tells a story about how she let Adam McKay sleep on her couch before he was famous because he couldn’t afford to stay in Chicago.
When I was doing my research on improvisation in the early 1990s, the theater was called “Improv Olympic” and only later renamed “iO.” Don’t tell anyone I said that.
