She also made an impact as the super snobby Mrs. Hutchinson in Liverpudlian flatshare comedy The Liver Birds from 1971 to 1979 (alongside Ivan Beavis as the long-suffering Mr. Hutchinson). She reprised the role in the short-lived 1996 revival.
Such was her popularity with the viewing public, Mollie fronted two of her own sitcoms: BBC space travel saga Come Back, Mrs. Noah (1977-1978), and the better-received That's My Boy (1981-1986) for Yorkshire Television.
Her numerous other television comedy credits include appearances in Steptoe and Son, Hugh and I, Up Pompeii!, The Goodies, Doctor at Large, Please Sir!, Doctor in Charge, Love Thy Neighbour and Little Britain. She also made forays into serious drama, with roles in Z Cars, The Six Wives of Henry VIII, Emma and The Bill.
