Following the June 23 performance of the long-running, Tony-winning revival of Kander and Ebb's Chicago at the Ambassador Theatre, Emmy Award nominee and "Grey's Anatomy" star Chandra Wilson will take part in a discussion and question-and-answer session.

Two-time Emmy Award nominee Samantha Harris ("The Insider," "Dancing with the Stars") will be the featured guest for the July 14 and Aug. 11 "Talkback"s.

All three discussions will be moderated by Chicago casting director Duncan Stewart.

The series, according to press notes, is designed to "provide theatregoers with an exclusive, behind-the-scenes glimpse into the world of Chicago."

Chandra Wilson will play Mama Morton in Broadway's Chicago June 8-July 5. Samantha Harris will play merry murderess Roxie Hart July 7-Aug. 16.

Tickets for the "Talkback Tuesdays" performances are available by calling (212) 239-6200 or by visiting www.telecharge.com.
