As explained by Contradiction's Thomas Harlan, the TV adaptation of Alan Wake isn't going to have its story follow alongside the game's version of the plot beat by beat, and Lake declined to comment whether or not the show's story will will tie into the overall continuity of the game's universe.
Lake's game was influenced by The Twilight Zone, Secret Window, Northern Exposure, masters of horror Stephen King and Alfred Hitchcock, and other television projects. "We plan to work closely with Sam on [this] show".
Although Alan Wake was released in May 2010 for the Xbox 360, the gaming population hasn't forgotten Wake's adventure through idyllic Washington. Sam is a huge part of this.
This is easier said than done however, as Wake quickly finds himself facing off against malevolent, shadow-like creatures in events that appear to have been plucked right out of the pages of his latest novel.
"Alan Wake was basically a TV series that was made into a game". While there have been no subsequent entries in the series since, Lake said in a 2015 interview (also with Variety) that he had bigger plans for the franchise. Harlan said a number of studios have already shown interest.
Hopefully the show will be just as good as the game. Alan Wake is a very central character, but we have other characters around him like [friend and agent Barry Wheeler] and his wife Alice and Sheriff Sarah Breaker and other characters there.
While Alan Wake fans should be intrigued by this project, neither Harlan nor Lake provided details relating to the television series' release date, as the show has yet to even be pitched. He also said that the story of the original game will serve as a baseline for the story of the TV show and it will then begin to expand and grow from there.
