Her major roles included Across the Bridge (1957), Dublin Nightmare (1958), First Man into Space (1959), The Murder Game (1965), and the Hammer films The Hound of the Baskervilles (1959, as Cecille Stapleton) and The Pirates of Blood River (1962). She was a Play School presenter from 1964-70. Joy Whitby, the programme's creator and earliest Producer, recalled in 2013: "She spoke English with a heavy accent, but she was very loveable and children adored her." Landi also presented Parliamo Italiano. She also appeared in an episode of the TV version of Hancock's Half Hour called "The Italian Maid" in 1959 though this recording was lost (although an off-air recording of the Soundtrack was recently discovered by Tristan Brittain-Dissont, Archivist of the Tony Hancock Appreciation Society).
In 1977 she married Sir Francis Dashwood, 11th Baronet. Together they lived at West Wycombe House in Buckinghamshire.
