While Kathleen Turner is on vacation from Broadway's hit comedy, The Graduate, Sept. 17-22, Linda Gray will take over the robe-dropping role of Mrs. Robinson.

Best known as J.R. Ewing's long-suffering wife, Sue Ellen, in the Emmy-winning TV hit, "Dallas," Linda Gray made her stage debut at Los Angeles' Canon Theatre in Love Letters. She also appeared in The Vagina Monologues in both L.A. and Atlanta. She played Mrs. Robinson during The Graduate's London run.

Jason Biggs and Kelly Overton will play Mrs. Robinson's conquest, Benjamin Braddock, and daughter, respectively.

It was also recently announced that Turner has lengthened her stay in the show in order to coincide with co-star Jason Biggs' contract. Biggs left the Broadway production June 10 in order to film a role in Woody Allen's new film. He returned to the show Aug. 20 but was asked to extend his run through Nov. 17 in order to compensate for the time spent on the film set. During his absence, the role of Benjamin Braddock is being played by film and TV actor Josh Radnor.

In other news, when Turner leaves the Broadway show for good, Lorraine Bracco will be the next actress to bare all. Turner departs Nov. 17 and Bracco begins Nov. 19. Bracco is a three-time Emmy Award nominee for her role as Dr. Jennifer Melfi on the hit HBO series "The Sopranos." This will mark the Broadway debut for the actress, who also received an Academy Award nomination for her work in "Goodfellas." Bracco's other screen credits include roles in "Even Cowgirls Get the Blues," "Silent Cradle," "Riding in Cars with Boys" and "Tangled."

Set in California in the 1960s, The Graduate — which was adapted and directed by Terry Johnson — is currently playing The Plymouth Theatre (236 W. 45th Street). Tickets — ranging from $21.25 to $81.25 — are available through Telecharge by calling (212) 239-6200.
