The Better Sister cast: Who stars in the Prime Video thriller?
Jessica Biel and Elizabeth Banks lead the new Prime Video drama.

What do you get when you pair a murder mystery with a complicated family history? Well, Prime Video's latest gripping drama, The Better Sister.
Based on the best-selling thriller novel of the same name by Alafair Burke, the new eight-part series digs into the aftermath of lawyer Adam's (Corey Stoll) murder that rocks his family.
Leaving behind his wife Chloe (Jessica Biel) and son Ethan (Maxwell Acee Donovan), all eyes turn to the inner workings of this seemingly perfect family as it's soon discovered that Aaron was actually married to Chloe's sister's Nicky (Elizabeth Banks) initially.
The pair of sisters are reunited after years in the wake of Adam's death, with the simmering tension all too palpable – but will they be able to set their differences and disagreements aside when a prime suspect is named?
Speaking of their dynamic, Banks told ScreenRant: "[Nicky] comes to the scenario with a lot of deception, but a lot of grace for her sister, and we have to flip that. I need her to help me with the lies and the deception, and I need grace from her."
But who's who in The Better Sister? Read on to find out more about the cast of the new thriller.
