Victory Gardens Theater announced this morning this year's celebrity playwrights for its annual Chicago Stories benefit. Sun-Times entertainment columnist Bill Zwecker, retired Tribune theater critic Richard Christiansen (also author of A Theater of Our Own, the definitive history of Chicago theater), and the husband and wife team of Attorney General Lisa Madigan and New Yorker cartoonist Pat Byrnes (writing a musical, no less!) will each author a ten-minute play to be directed by VGT artistic director Dennis Zacek. This year's class joins such illustrious (and often first-time) playwrights as John Mahoney, Phil Jackson, Mike Royko, Carol Mosely-Braun and Jesse Jackson—last year's writers were Rick Bayless, Alpana Singh, and Tribune columnist Rick Kogan. The benefit is May 4; see Slowdown for details.
