The Otho Eskin drama in "on track" to transfer to Circle in the Square in early March, said the spokesman. If the work indeeds reaches the Great White Way, it will be the Cinderella story of the season. Eskin, a one-time diplomat, is an unknown quantity as a playwright, and the show's two featured players, Laura Esterman and Pamela Payton-Wright, while respected actors, are not marquee stars. Furthermore, the play opened to unprepossessing reviews.

Despite these perceived drawbacks, Duet has proved a hit at the tiny Greenwich Street Theatre. The drama began previews on Nov. 18 toward an opening Dec. 4. It was to have ended its life on Jan. 4, but prolonged its run to Jan. 18, and then Jan. 25.

Ludovica Villar-Hauser is the show's director and producer. She previously trasformed the long-running Off-Broadway play The Countess into an unexpected hit."This process will mirror the route taken by The Countess," Villar-Hauser told Playbill On-Line in a statement. "We'll be moving from a small theatre, the Greenwich Street, to a larger opportunity (the extension), to a much larger opportunity (the reopening)."

During the extension at the Greenwich Street, the company will be working on revisions to the script.

Esterman, who has acted in Marvin's Room, Good as New, Freedomland and Cranes, plays The Divine Sarah. Payton-Wright, who was recently seen in Fifth of July and spelled for Vanessa Redgrave during her brief absence from Long Day's Journey Into Night, is La Duse. The two thespians were considered the greatest actresses in the world during much of their lifetimes (Bernhardt died in 1923; Duse, who was much younger than Bernhardt, passed away in 1924). Artistically, however, they couldn't have been more different. The French Bernhardt's fame, established in melodramas by Dumas fils and Sardou, was firmly rooted in the cult of personality that surrounded her. She struck beautiful poses and hit her dramatic "points" like clockwork. With her sculpting career, many lovers and habit of sleeping in a coffin, she made for consistent newspaper fodder.

Duse, meanwhile, pursued a modern playing style in the plays of her lover Gabriele D'Annunzio and Henrik Ibsen. Critics noted her naturalistic, integrated playing style, her eschewing of make-up, corsets and jewelry, and her ability to find the drama between the words and in long silences. She ostentatiously abhorred publicity, though she cultivated the favor of critics and editors privately through flattering letters.

The two were great rivals, and with good reason. Their repertoires often overlapped; The Lady of the Camellias was a huge success for both. D'Annunzio, Duse's longtime lover, gave his first play to Bernhardt. In 1895, both actresses simultaneously appeared in competing London productions of Hermann Sudermann's Heimat, resulting in a famous review in which George Bernard Shaw compared the two (he preferred Duse). A couple years later, Duse made her debut in Paris, the Divine Sarah's kingdom. Bernhardt graciously allowed her rival to use her very own theatre, but was infuriated when Duse revealed a repertoire consisting of the French actress' greatest hits.

The play depicts a surprise encounter between the two; the ghost of the recently deceased Bernhardt visits Duse in her dressing room just before a Pittsburgh engagement (after which Duse would fall sick and die herself). Also featured in the play, as the various men in the two divas' lives, is Robert Emmet Lunney.
