In the movie, The Green Mile, I knew instantly that the small, "magical" like mouse had some sort of symbolic meaning but I cannot for the life of me think of what that meaning could be. Does anyone know why or how the mouse is symbolic or have any idea of what the mouse represents?
I've always thought of the mouse as a storytelling vehicle to show us a few things: the humanity and kindness that still resides in the hearts of the convicted murderers in the Green Mile (and by contrast the inhumanity and cruelty of Percy) and to allow John Coffey to demonstrate his healing powers.
Del's crimes are heinous, yet he still shows a child like wonder at the mouse's intelligence and adopts it as a friend. The guards know Del's crimes, yet they help him take care of the mouse joined as they are by a bond that is very human. Percy, on the other hand, doesn't share that bond. He may not have been convicted of any crimes, yet his inhumanely cruel nature bars him from bonding with the prisoners and the mouse, as he sees both as targets for him to exercise his power. This is shown by him attempting to kill the Mouse and torture Del on the electric chair.
With the mouse mortally wounded, Coffey gets to show us his healing powers. He not only revives him, but also as we see later on imbues him with a longer lifespan.
