Born in 1922, Hattie Jacques began her career in music hall before graduating onto the radio comedies of the 1950s such as Educating Archie, It's That Man Again and Hancock's Half Hour where she became a star. TV and films followed, most notably the role of Eric Sykes's twin sister in Sykes and the stern but lovelorn matron, headmistress or housekeeper in the Carry On films.

Hattie was teased about her weight in school and she was often the person being laughed at in her work. She largely accepted this role but yearned to do more serious work. In contrast to many of the characters she played she was a vivacious person who loved men and liked a party.

Choosing Hattie is neuroscientist Sophie Scott who remembers Hattie as the first funny woman she heard or saw. Sophie studies why we laugh and says it was great how Hattie held her own with these men. Together with expert Andy Merriman they explore Hattie's life including how she did her own welding in a film, her marriage to John Le Mesurier and affair with John Schofield, and whether the typecasting she suffered was a hindrance or a benefit to her career.

Presented by Matthew Parris, who remembers Hattie uttering "But not with a daffodil!" in Carry On Nurse. You'll have to listen to find out where exactly that daffodil was discovered.
