The photo of the young Red on his "Approval" document is a photo of Morgan Freeman's son. It was a police photo of him after he was convicted for joyriding.

There are many references to the number 237 in the movie. For instance, this is the number of Red's cell, and these digits are on Andy's prison I.D. This number makes appearances throughout Steven King stories, the most famous one being the room where the murders take place in "The Shining".

Originally, the film was supposed to end before Red and Andy met again. The last shot was of Red's narration saying, "I hope the Pacific is as blue as it is in my dreams." After a huge argument, a few final shots of Red meeting Andy on the beach were added in.

The sound of the warden shooting himself is the same sound of the man stamping "Approved" on Red's paper.

The Humane Society had to be present for the scene when the maggot is feed to the bird, Jake. The Society said it was cruel to the maggot, so it had to get a maggot that died of natural causes before the crew could shoot it.
