The great composer Stephen Sondheim loved puzzles, and when he died in 2021, he left one for his good friend, British super-producer Cameron Mackintosh.

McKellen won a special Olivier — his seventh — for his one-man 80th birthday tour of the U.K., staged before the pandemic as a fundraiser for regional theaters. A handful of theaters have reopened to reduced, socially distanced audiences, but many are still shut and relying on emergency funding from the government to stay afloat. Olivier organizers say the next awards ceremony will likely not be until 2022, because so little work has been staged this year.
