Let the Right One, which premieres Sunday on Showtime, follows Eleanor Kane (Madison Taylor Baez), who ten years prior was turned into a vampire and thus stuck forever as a twelve-year-old, only able to leave at night. Her father, Mark (Demián Bichir) does his best to continue to provide her with the blood she needs, but things become more challenging when they become entangled in the lives of those around them, including Isiah Cole (Ian Foreman) who wants to be friends with Eleanor.
The ten-episode series was inspired by the original Swedish novel and film of the same name. When adapting the story for the new series, showrunner and executive producer Andrew Hinderaker started with the connections between the characters. “The [original] movie is not only one of, for me, the best horror movies ever made, but probably the most moving, and that's how I always begin, with an emotional connection,” he told SciFi Vision during a recent TCA panel. “I think that, in the film, the relationship between those two children…is just astonishingly beautiful and poignant and poetic, and so there's an opportunity to use that as an aesthetic inspiration.”
“What's sort of extraordinary about the film is it also felt like there was real creative space to build upon what was already there,” he added. “So, for example, there's sort of a small relationship between the character, the child vampire, and her caretaker, who fetches her blood. For me, personally, as a person, as an artist, I was really interested in exploring addiction and exploring what a parent will do for a child when they are struggling with addiction. It felt like this incredible gift to take what was in the foundations and in the sort of seeds of the film and create an entirely new story that would be centered around Demián's character Mark and Madison's character Eleanor and explore the lengths that this father would go to keep his daughter alive.”
