In the Nightmare sequence at the beginning of the game, Alan Wake is being chased by a hitchiker he had written and killed off in one of his books, not unlike the relationship between Beaumont and Stark.
The protagonist, an author, is kidnapped and forced to write a book he doesn't want to write. Also, Thad strikes George with a typewriter, just as Paul defends himself against Annie in "Misery."
The game is a spin off from the movie, but it came out first to promote the film's release. It is based on both the source novel and the film adaptation.
