The Better Sister, based on the book by Alafair Burke, premiered on Prime Video on May 29, 2025. It follows the investigation of the brutal murder of high profile lawyer Adam Macintosh (Corey Stoll) and the devastating impact it has on his family: wife Chloe (Jessica Biel), son Ethan (Maxwell Acee Donovan), and ex-wife, who also happens to be Chloe’s sister Nicky (Elizabeth Banks). While the police arrest Ethan for the crime, the truth is far more complicated. The eight-episode series explores themes of sibling rivalry, domestic violence, public perception versus private existence, and what it means to be an unreliable narrator. 

We touched base with showrunners Olivia Milch and Regina Corrado to talk about those themes. From the idea that siblings grow up with different versions of the same parents, to peeling back the “layers of the onion of the mystery”, Milch and Corrado describe what goes into developing a series like The Better Sister.
