The star of Good Girls discusses Mad Men, sexual harassment and squaring her glamorous reputation with her ‘weird, goofy’ personality

Christina Hendricks appears on our video call with the most dramatic backdrop. Art deco gold peacocks bedeck a black wall, making her look, as she has so often in her career, a bit too good to be human. Perfectly poised, perfectly framed, perfectly lit, she is more like a dreamy vision of what humans look like. “I, erm, like your wall,” I say, pointlessly. She flashes a smile, as if to say: “Obviously.”

We are here primarily to discuss the comedy-drama series Good Girls, the fourth season of which will resume in the US this month after a midseason break. The elevator pitch would be Breaking Bad for girls: three suburban women, each hovering on the edge of bankruptcy, unite to embark on a life of cack-handed crime, only to discover they are good at it. The ensemble – Hendricks, Mae Whitman, who plays her sister, and Retta, their friend – works strikingly well, their pacey comic rapport instilling a sense of perpetual motion. You just can’t imagine Good Girls ending. Every time a plot line seems to be reaching its climax, something worse – and funnier – happens.
