Her successes in theatre include the Royal Court Theatre and Broadway productions of Home. Her big screen debut was in Hue and Cry, in 1947, followed with performances in Nicholas Nickleby, The Fallen Idol, The Winslow Boy, The History of Mr Polly, Scott of the Antarctic, Mother Riley Meets the Vampire and Dickens' The Pickwick Papers.
Till Death Us Do Part came to an end in 1975 but was revived in 1981, entitled Till Death..., and again in 1985. Dandy agreed to appear, but had been suffering from rheumatoid arthritis and had to use a wheelchair. Her illnesses were written into the scripts, and the series was appropriately renamed In Sickness and in Health.
Dandy Nichols was married to the newspaper Editor Stephen Bagueley Waters in 1942 but the marriage ended in divorce in 1955 due to his adultery. Nichols was an atheist most of her life. Her poor health led to a fall in her flat and she died of pneumonia and heart disease on 6 February 1986 aged 78 at the London Hospital, Whitechapel three days later.
