## Production
### Development

A television adaptation based on the 2004 novel, Let the Right One In, by John Ajvide Lindqvist was in development for A&E. On August 29, 2016, the pilot was in development at TNT as an eerie drama following the same premise as its predecessor. On April 13, 2017, TNT announced they had scrapped the pilot and were shopping the series to other networks in its current iteration or a potential redo.
On March 15, 2021, Showtime ordered a pilot for the series, with Andrew Hinderaker serving as showrunner. On September 22, 2021, the show was ordered as a 10-episode series.
In an October 2022 interview, Ajvide Lindqvist mentioned he was not involved with the show, explaining that he inadvertently sold all rights to the book for only 1 SEK when he thought he was only giving Hammer Films the rights to make Let Me In (2010), the American remake of the 2008 film adaptation of the book, meaning he will earn no royalties from the TV show; according to him, Hammer had misled him about the nature of the contract, saying "there were thick bundles of American legal prose. And that would then mean that I sold all the rights for a penny, but that was just a mere formality and would have no practical meaning, they said." On January 30, 2023, Showtime canceled the series after one season.

### Casting

Kristine Froseth was cast in the TNT iteration of the pilot as the lead, Eli, on September 29, 2016. On October 13, 2016, Benjamin Wadsworth and Thomas Kretschmann were tapped to star as the other leads, Henry and Inspector Eriksson, respectively. On October 20, 2016, Necar Zadegan and Cameron Gellman joined the pilot in the series regular role FBI Special Agent Sarah Church, and the recurring role of Kyle, respectively. Darren Mann joined the pilot in a recurring role as Lukas on October 25, 2016. The pilot at TNT was eventually scrapped in April 2017 before entering production.
On March 15, 2021, Demian Bichir signed onto the pilot as the lead, now in development at Showtime. Anika Noni Rose joined the main cast as Naomi on April 15, 2021. Grace Gummer joined the main cast as Claire on April 29, 2021. Nick Stahl was cast as a series regular as Matthew on January 26, 2022. On June 17, 2021, Madison Taylor Baez was cast in the lead opposite Demián Bichir as Eleanor. Kevin Carroll, Jacob Buster and Ian Foreman were also amongst the new cast additions. Željko Ivanek & Fernanda Andrade joined the series in recastings as Elizabeth and Arthur, respectively. Larry Pine and Susan Santiago played their respective roles in the pilot. Jimmie Saito, Josh Wingate, and Caroline Neff joined the series in recurring roles as Ben, Roland, and Danielle Wilson, respectively.
