The new comedy by Theresa Rebeck, Poor Behavior, opened last night, August 17th, at the Duke on 42nd Street. The play features Heidi Armbruster, Brian Avers, Jeff Biehl and Katie Kreisler and is directed by Evan Cabnet. It’s a story about infidelity and America; a devilish argument about two couples spending a not-so-idyllic weekend in the country! Here are opening night photos by JK Clarke.
