Based on the Alafair Burke bestselling novel, The Better Sister is centered on Chloe (Jessica Biel) and Nicky (Elizabeth Banks), two estranged sisters whose lives diverged after a traumatic incident involving Nicky’s loss of custody of her son, Ethan (Maxwell Acee Donovan), to her then-husband Adam (Corey Stoll). Years later, Chloe is married to Adam and raising Ethan as her own. When Adam is brutally murdered, suspicion falls on Ethan, drawing Nicky back into the family’s orbit.

Olivia Milch and Regina Corrado, who served as showrunners and executive producers on the series, recently spoke with SciFi Vision about adapting the novel for television, casting, and more.
