Arguably one of the best vampire tales in recent memory is the 2008 Swedish film Let the Right One In, which told of the story of a bullied 12-year-old boy named Oskar, and his oddly touching relationship with the undead Eli, a centuries-old vampire stuck in the body of a child. Directed by Tomas Alfredson, Let the Right One In was itself an adaptation of the 2004 novel of the same name, with book author John Ajvide Lindqvist writing the screenplay himself. A critical darling and award magnet, Let the Right One In was considered by many to be the best horror film of 2008, as well as one of the best horror films of its entire decade.
Let the Right One In was subsequently adapted for American audiences in 2010 by future Batman director Matt Reeves, and given an altered title of Let Me In. This version -- starring Chlöe Grace Moretz -- earned mostly positive reviews as well, but hasn't proved to have quite the staying power within the genre community as its progenitor.
In 2015, A&E announced plans to adapt Let the Right One In for TV, with the project then hopping networks to TNT in 2016. Unfortunately, Deadline now reports that TNT has decided not to move forward with the project, although production company Tomorrow Studios reportedly plans to shop it around elsewhere.
Despite being officially ordered to pilot by TNT last summer -- and casting its lead roles in the fall -- Let the Right One In's potential TV adaptation never actually ended up entering production. Working from a script by Criminal Minds and Teen Wolf creator Jeff Davis, Let the Right One In's TV incarnation was said to be based directly on Lindqvist's book, albeit with the two main characters aged up and the setting moved to a small town in Vermont. Oskar's name was also set to be changed to Henry.
It remains to be seen whether Let the Right One In's TV series will eventually rise from the dead on another network, but considering that it's already gone through two of them, the chances it'll cheat death yet again probably aren't the greatest. Let the Right One In isn't the only vampire movie-based show to hit a snag in as of late though, as The CW recently opted to push back the development of its TV series adaptation of The Lost Boys to 2018.
