Kathleen Turner — who last hit the Rialto playing Martha in “Who’s Afraid of Virginia Woolf?” — is in talks to return to the stage as a recovering alcoholic nun.Turner’s agent confirmed the actress is in negotiations to star in the premiere of Matthew Lombardo’s three-hander, “High,” which is expected to bow in June at a theater yet to be announced, followed by several other venues. There is also commercial attachment to the project, according to the playwright, whose “Looped,” starring Valerie Harper as Tallulah Bankhead, begins Broadway performances Friday and opens next month. “Looped” helmer Rob Ruggiero will direct “High,” which centers on a nun and the 19-year-old drug addict she is trying to help. The third character is a priest who runs the treatment facility. Turner’s Rialto credits include “Cat on a Hot Tin Roof” and “The Graduate.” She also directed a revival of Beth Henley’s “Crimes of the Heart” at the Williamstown Theatre Festival and then Off Broadway. Her screen roles include “Body Heat,” “Romancing the Stone,” “War of the Roses,” “Prizzi’s Honor,” “Peggy Sue Got Married,” “Serial Mom” and “Marley and Me.” On TV she had returning roles in “Friends” and “Californication.” Along with “Looped,” Lombardo scripted the one-hander “Tea at Five” about Katharine Hepburn. Kate Mulgrew toplined a 2003 Off Broadway production that has since toured other venues.
