As part of one of its most populist seasons in years, Ontario’s Shaw Festival will present all 10 plays that make up Noel Coward’s “Tonight at 8:30” series, including the rarely produced “Star Chamber.”

It will mark the first time that all of the plays have been produced in repertory by a professional company since their London debut at the Phoenix Theater in the 1935-36 season, according to Shaw a.d. Jackie Maxwell. Plays will be presented in three groups, one at each of the Festival’s three theaters, and on two occasions it will be possible to see all 10 on a single day, in an event christened “Mad Dogs and Englishmen.”

Another novel feature of the season is the presentation of John Osborne’s “The Entertainer” in a fourth performance space created from one of the fest’s rehearsal halls.

Shaw himself will be represented by “The Devil’s Disciple” and “In Good King Charles’s Golden Days,” while other works on the bill include Garson Kanin’s “Born Yesterday,” Stephen Sondheim and James Lapine’s “Sunday in the Park With George,” Eugene O’Neill’s “A Moon for the Misbegotten” and Michel Tremblay’s “Albertine in Five Times.”

Season begins previews on April 1, opens May 20 and runs until Nov. 1.
