“Teen Wolf” isn’t over yet, but the cast and crew are already thinking about the future. For showrunner Jeff Davis, that means creating a new series. It looks like the scribe is once again adapting a movie for television.

Davis will helm “Let the Right One In,” Variety reports. He’ll write a pilot in order for TNT to decide if they want a full season. The series is an adaptation of John Ajvide Lindqvist’s 2004 novel of the same title. The story follows Oskar, a 12-year-old dealing with bullies at school. He finally finds a friend when he meets Eli, a girl who seems to be is age. He quickly realizes that she is a vampire and is connected to gruesome murders in their town.

If the story sounds familiar, that’s because this won’t be the first adaptation of the book. It was a critically-acclaimed Swedish film in 2008. In 2010, another movie was made for English-speaking audiences starring Chloe Grace Moretz and Kodi Smit-McPhee. A stage version of the story was also successful on London’s West End.

The new TV show might diverge from the source material. Davis previously adapted “Teen Wolf” from the 1986 comedy of the same title, but viewers have a hard time finding similarities between the two other than having teenage werewolves.

Some longtime “Teen Wolf” fans will likely find Davis’ switch from werewolves to vampires amusing. The MTV drama, which will end in 2017 after six seasons, has included a vast array of supernatural creatures, but vampires never made it onto the show. That was very intentional.

“We’re werewolves for now,” Davis told E! Online in 2012. “I always say there will be no vampires on the show, but ask me in five years when we run out of ideas.” Unless there’s a big surprise in Season 6, it looks like Davis will manage to finish the teen show without including any blood suckers.

Even though the creatures are different, “Let the Right One In” sounds like familiar territory for Davis. Not only is it creepy, but it sounds like it’ll have some teen romance too. “‘Let the Right One In’ combines elements of horror, revenge thriller and adolescent romance into an unforgettable and truly unsettling tale,” Sarah Aubrey, TNT’s executive vice president of original programming, said in a statement.

TNT has not announced when “Let the Right One In” would premiere if it’s picked up for a full season.
