 SPOILER: In the scene after Andy has escaped, the warden wants them  to question Red. When they call to open Reds cell they shout, "Open  237!" This is the same number as the room in  _Shining, The (1980)_ (qv) and the amount of change ($2.37) the four  boys in _Stand by Me (1986)_ (qv) collect between them. All three  movies were based on Stephen King (I) (qv) stories
