It didn’t end there. Sadler, a standup turned TV joke writer, immediately started work on a script inspired by their conversation, and three years later it has become the sitcom Such Brave Girls – hands down the funniest British comedy of the year. It stars Sadler as twentysomething Josie (nervy, indecisive, people-pleasing, recently sectioned and coming to terms with her sexuality) and Davidson as her younger sister Billie (aggressive, vain, dangerously obsessed with her on-off boyfriend Nicky). It is pitch-black, hysterically funny and brutally unsentimental – a zillennial Nighty Night.
