Q: Passage: The following year Mount appeared in two films: she played Police Sergeant Fire in Dry Rot, an adaptation of a Whitehall farce, and she reprised the role of Emma Hornett in a film version of Sailor Beware!. Over the rest of the 1950s her career included stage, cinema and television work. She played the cameo role of the Charwoman in Diego Fabbri's religious drama Man on Trial at the Lyric Theatre, London in 1957. In the same year she starred with Terry-Thomas and Peter Sellers in the comedy film The Naked Truth. From 1958 onwards she became a regular television performer, first, opposite Richard Hearne, as a landlady in The Adventures of Mr. Pastry, and then in a central role in The Larkins, an early ITV comedy series featuring David Kossoff and Mount as a suburban London couple, Alf and Ada Larkin, and their family. Six series of the show were made between 1958 and 1964, and the leading characters, the put-upon but wily Alf and the formidable Ada, appeared in three spin-off feature films between 1958 and 1960. In a 1958 television version of Arsenic and Old Lace Mount was cast against type in the role of the well-meaning poisoner Abby Brewster. Her last stage role of the 1950s was Florence Povis in Farewell, Farewell, Eugene at the Garrick Theatre in June 1959, co-starring with Margaret Rutherford.
