"

As the nanny in Chekhov's Uncle Vanya (1996, Chichester) with a cast that included Derek Jacobi, Imogen Stubbs, Trevor Eve and Frances Barber, Mount gave what her biographer Verena Wright calls "a great performance as the play's most sympathetic and sensible character".[4] This production played on a provincial tour and at the National Theatre. It was Mount's last play. During a performance her sight, which had been deteriorating, failed completely. She managed to finish the performance, after which she retired from the theatre.[2]
