in a revival of John Home's tragedy Douglas at the Edinburgh Festival (1950), and without Casson, Thorndike starred with her old friend Edith Evans in N. C. Hunter's Waters of the Moon. The play, described by Croall as "a cosy middle-class drama [with] certain elements of Chekhov", received tepid reviews but proved popular with audiences and ran for 835 performances at the Theatre Royal, Haymarket between 1951 and 1953. The Cassons rejoined forces in Hunter's next play, A Day by the Sea (1953), directed by and co-starring John Gielgud. Like its predecessor, the play appealed more to the public than to the critics, and ran for 386 performances at the Haymarket. During the mid- and late-1950s Thorndike and Casson were seen more abroad than at home. They toured the Far East, New Zealand and India in 1954, giving dramatic recitals. Together with Richardson they toured Australia and New Zealand in 1955, presenting The Sleeping Prince and Separate Tables. The couple toured southern Africa, Kenya, Israel, and Turkey in 1956, giving dramatic recitals. In the West End in June 1956 Thorndike played Amy, Lady Monchensey in The Family Reunion, with Casson, Paul Scofield and Gwen Ffrangcon-Davies. In New York the couple appeared in the world premiere of Graham Greene's The Potting Shed, which ran on Broadway for 143 performances in 1957, after which they revisited Australia and New Zealand, touring in The Chalk Garden. During the 1950s Thorndike appeared in eleven films: Stage Fright (as Mrs Gill, 1950), Gone to Earth (Mrs Marston, 1951), The Lady with a Lamp (Miss Bosanquet, 1951), The Magic Box (the Aristocratic Client, 1951), Melba (Queen Victoria, 1953), The Weak and the Wicked (Mabel, 1953), The Prince and the Showgirl (The Queen Dowager, 1957), Alive and Kicking (Dora, 1958), Smiley Gets a Gun (Granny, 1958), Shake Hands with the Devil (Lady Fitzhugh, 1959) and Jet Storm (Emma Morgan, 1959). Among her television appearances was a studio production of Waters of the Moon with Evans, Casson and Kathleen Harrison. Later years, 1960–1976 Thorndike's first stage role of the 1960s was Lotta Bainbridge in Coward's Waiting in the Wings; she and Marie Löhr played the lead roles of two residents in a retirement home for actors and actresses, perpetuating, and finally resolving, an ancient feud. She said of it, "I loved that play. It's the most lovely modern play I've played", but the piece was not a great
