She played Doris Ewell in the television comedy series Please Sir! (1968–72) and Mrs Pugh Critchley, in the series All Gas and Gaiters (1970–71), as well as a role in the short-lived sitcom Wild, Wild Women (1969). However, she is probably best known to many for a single guest role: that of the abrasive and selectively deaf Mrs. Richards in Fawlty Towers (episode: "Communication Problems"). She was also in After Henry, a gently comic series on both radio (1985–88) and television (1988–92), in which she played the domineering Eleanor, mother of Sarah (Prunella Scales), who lives below her in the basement flat in Sarah's large house. Her movie roles were rare but she appeared in the Hylda Baker film She Knows Y'Know (1962), Who Killed the Cat? (1966), the film version of Please Sir! (1971), The Great Muppet Caper (1981), playing John Cleese's wife, and Prick Up Your Ears (1987), the film based on the life of Playwright Joe Orton.
