Starring Demián Bichir, Anika Noni Rose, Grace Gummer, Madison Taylor Baez, Kevin Carroll, Ian Foreman and Jacob Buster. Stream the premiere October 7. Inspired by the original hit Swedish novel and film,the series centers on Mark (Bichir) and his daughter Eleanor (Baez), whose lives were changed 10 years earlier when she was turned into a vampire. Locked in at age 12, perhaps forever, Eleanor lives a closed-in life, able to go out only at night, while her father does his best to provide her with the human blood she needs to stay alive. With these emotionally charged and terrifying ingredients as a starting point,LET THE RIGHT ONE INwill upend genre expectations, turning a naturalistic lens on human frailty, strength and compassion. Led by Oscar nominee Demián Bichir (A Better Life), the series also stars Tony winner Anika Noni Rose (Dreamgirls, Power), Grace Gummer (Mr. Robot), Madison Taylor Baez (Selena: The Series), Kevin Carroll (Snowfall), Ian Foreman (Merry Wish-Mas) and Jacob Buster (Colony). Award-winning playwright, writer and producer Andrew Hinderaker (Away, PENNY DREADFUL), who wrote the pilot, will serve as showrunner and executive produce along with Seith Mann (HOMELAND, FreeRayshawn, Blindspotting), who directed the pilot and will also direct additional episodes.
