The film Joy, out on Netflix Nov. 22, follows what went into the landmark development of in-vitro fertilization, with a focus on one woman who helped pioneer the treatment. Joy is at once about IVF as it is about Jean Purdy (Thomasin McKenzie), a nurse who was part of the team that facilitated the birth of Louise Brown, the first “test tube” baby, along with the physiologist Robert Edwards (James Norton) and Patrick Steptoe (Bill Nighy), a pioneer of laparoscopy in gynecology in the UK. [time-brightcove not-tgx=”true”] The film depicts Purdy as suffering from a case of endometriosis that prevents her from becoming pregnant.
