Broadway has lost its biggest hit play. The producers of The Blue Room have canceled the smash show's remaining performances due to star Nicole Kidman's illness. Kidman was out all last weekend, felled by a bronchial infection that inflamed her vocal cords. Since then, the actress has been instructed by doctors to rest her voice for three weeks.

Blue Room, an adaptation by playwright David Hare of Arthur Schnitzler's La Ronde, was to have run through Mar. 7. It began previews on Nov. 27, 1998 and opened Dec. 13. It will have played 15 previews and 82 performances at Broadway's Cort Theatre.

"The Blue Room has brought such joy to me the last six months," Kidman said in a statement. "I am truly devastated not to complete the last week of the run and deeply apologize to the people who have planned to attend those performances."

Ticketholders for the remaining shows can obtain refunds by returning their tickets to the Cort Theatre box office, at 138 W. 48th St., or by mailing them to: P.O. Box 998, Times Square Station, New York, NY 10108 0998. Ticketholders should include credit card information and a billing address in their mailings.

The Blue Room began life in London, where it created a sensation, in no small part due to a brief scene in which Kidman appeared nude. The play also starred Iain Glen. Sam Mendes directed.
