The production, marking the company's 21st summer season, had been scheduled to run weekends from August 15 to September 7.
Michele Delattre, the Curtain's artistic director as well as director of the production, said the move by the organization's board of directors came after extensive discussion of the options and a survey of cast members.
"A lot of painful thought went into the decision," Delattre said.
The company has been rehearsing for months in online sessions and has posted a series of in-rehearsal videos and interviews on its website. Delattre expressed confidence that the current cast will be able to return next year to mount "Twelfth Night" when conditions are safer for audience, cast and community.
"I’ve been in the enviable position of getting to see all the backstage production work, music composition, choreography, set and costume designs as well as the actors’ storytelling," Delattre said. "We have the makings of a truly splendid production."
Delattre said the group hopes to keep the creative process continuing during the year ahead, likely through staged online readings and interviews and other activities to be announced later.
