Vanessa Redgrave’s much-anticipated return to the Royal Shakespeare Company after 43 years has been canceled. “Redgrave, 68 this month, was to have opened in a new version by Tony Harrison of Euripides’ tragedy Hecuba at the Royal Shakespeare theatre on February 17. Rehearsals for the play’s chorus began in London last week. The run has been scrapped to give her time to recover from an operation.”
