The lore behind FNAF...
This video will give you a full explanation of all the lore behind the FNAF series. Game Theory gives a lot of great information on the Freddy's franchise, so they are also a good source for info on the movie and game. There's several instances in the movie where the lore connects, like when the character Springtrap dies from a spring-lock failure. Another instance where the lore connects is when the 5 missing children show up in Mike's dream as ghosts. These instances happen in both the game and movie, so the movie does a good job of connecting the story together.
