Most famous for her supporting role as Daisy, the sister of Patricia Routledge's Hyacinth Bucket in the hugely popular BBC sitcom Keeping Up Appearances (1990), Judy Cornwell's grandmother was the music hall singer Sarah Bonner. The London-born actress grew up in England, where she attended a convent school before moving to Australia where her parents, Darcy Nigel Barry and Irene McCullen Cornwell, emigrated. She became a classical stage actress whose theatrical career began as a dancer and singer in pantomime, vaudeville, cabaret and musical revues. She has written a number of novels including "Cow and Cow Parsley" (1985), "Fishcakes at the Ritz" (1989), "The Seventh Sunrise" (1994) and "Fear and Favour" (1996). According to Cornwell, John Nathan-Turner was hoping to make a film of "Fear and Favour" before his untimely death at the age of 54 in 2002.
