Ms. Roth didn’t have an exact figure for this week so far, but said ticket sales are on track to “double” recent grosses. On Wednesday night, the house was nearly full, and audience members gave the cast a long standing ovation. Rebecca Taichman, the Tony-winning director, was in the house that night for what she thought was her last time before leaving for Vermont on Thursday.

“Indecent” tells the story of the Yiddish play “God of Vengeance,” an early 20th-century work by Sholem Asch that featured the first kiss between two women on Broadway and was promptly shut down, its cast and crew charged with obscenity. This was Ms. Vogel’s debut on Broadway at age 65 (after seasons in the New York theater world ) and a passion project developed with Ms. Taichman.

But neither Ms. Vogel’s prestige nor the production’s Tony wins could bring enough audience members to justify a long run on Broadway. Ms. Roth said she was unhappy with the play’s closing, and had lost sleep over it. “I just felt it hadn’t lived the life it needed to live,” she added.

As ticket sales increased after the closure was announced on June 14, Ms. Roth said, she began to toy with the idea of keeping “Indecent” open. In the past, shows have closed and reopened after a hiatus, often in smaller theaters. But the Cort was available, as were the actors — so the stars aligned to stay put, Ms. Roth said.
