The Number 237 Makes An Appearance
If you’re familiar with Stephen King’s work, you’ll know that he enjoys hiding Easter eggs in his stories and connecting them in some way. The number 237 is a minor tidbit that he has scattered throughout some of his books. When the guards cry “Open 237!” before asking Red about where Andy went, Frank Darabont opted to include this in the film. The number 237 also corresponds to the room in The Shining and the amount of money the guys have in Stand By Me.
