The producers of Agatha Christie’s The Mousetrap in London’s West End have “employed two casts who will rehearse and work completely separately, and appear in alternating runs of three performances. If an actor were to test positive, the other cast – contracted to be available and in reach of the theatre in their time off – will immediately take over for 10 days while the other group recuperates. Quarantine rules would prevent the usual theatre practice of one absentee being replaced by a stand-in.” – The Guardian
