Her career took off in the late 40's and for many years she was a major star. Having conquered cinema in that period she went on to have a 1960's TV serial "Mrs Thursday" and continued to work into her old age. She made many films perhaps one of my favourites (and most typical of her roles) was "Bank Holiday" (1937) (US: "Three on a Weekend").
Kathleen died 7th December 1995, aged 103!
