The corpse sitting in front of the distorted television set in the apartments is the same character model as James Sunderland. The clothes, body structure and face are the same - The camera is designed so that the player cannot see this, however.
The Blue Creek apartment building in Silent Hill is a reference to the film Blue Velvet (1986). "Blue", for the movie's title; and "Creek" as a synonym for "River", for the Deep River apartments seen in the film. The apartments in the game are very similar to the look and overall layout of the Deep River apartments in the David Lynch film.
Although not appearing in the game, several deleted scenes can be found in early trailers for the game, including a scene of Pyramid Head dragging a nurse away, and Laura singing "Ring Around the Rosie".
