- Freddy Fazbear´s Pizza is in Alkaine (Washington), a fictional small city that is supposed to be frontering with Canada.
- The movie was originally thought to follow the history of the game with Mike as the protagonist. Instead, the final version of the movie shows a new story similar to "The Silver Eyes" (A group of kids trying to survive to the Purple Guy and the animatronics) but very different at the time.
