The producer of “The Miracle Worker” has issued a public plea for theatergoers to turn out in support of the current Broadway revival.

Show opened March 3 to a mixed bag of press responses, with some positive notices balanced by a notably tepid review in the New York Times.

“The box office has not ignited as we had hoped,” producer David Richenthal said in a statement. “But we will continue in good faith with a call to arms for anyone who has been waiting to see it to act now.”

Richenthal made a specific appeal to family auds, who have been particularly responsive to helmer Kate Whoriskey’s staging of the 1959 William Gibson play about Helen Keller. Production stars Abigail Breslin, the 13-year-old thesp who is popular with young girls, as Helen and Alison Pill as teacher Annie Sullivan.

Richenthal ended his statement by acknowledging that he and his producing team will make a decision on whether to shutter the production based in large part on weekend sales. “If we don’t witness a significant increase in the box office over the weekend we will need to take a close look at our ability to keep the production open,” he said.
