Film choice

Saint Frances (Alex Thompson, 2019), 11.15pm, Film4
Kelly O’Sullivan scripts and stars in a wonderfully frank film centred around women’s health issues. She plays Bridget, 34, a waitress with little in the way of maternal instinct, who gets a job nannying cute but wilful six-year-old Frances (Ramona Edith Williams), while one of the girl’s two mothers, Maya (Charin Alvarez), struggles with her new baby. There is plenty in the relationship between Bridget and Frances to captivate, but the film is most interesting when it deals with the women and their problems – menstruation, abortion and postpartum depression: all topics getting an all-too rare airing on screen.
