Hope.

I never realized how much I love this movie, It's allusions to light and dark, freedom and confinement, life vs. death, the even idea that hope can carry you through 19 years of being in a cage, It's one of those movies you leave, feeling like a better human being, without really knowing why, its just a feeling you can't shake and frankly, you don't want too.

Red: [narrating] I have no idea to this day what those two Italian ladies were singing about. Truth is, I don't want to know. Some things are best left unsaid. I'd like to think they were singing about something so beautiful, it can't be expressed in words, and makes your heart ache because of it. I tell you, those voices soared higher and farther than anybody in a gray place dares to dream. It was like some beautiful bird flapped into our drab little cage and made those walls dissolve away, and for the briefest of moments, every last man in Shawshank felt free.

Andy Dufresne: That's the beauty of music. They can't get that from you... Haven't you ever felt that way about music?

Red: I played a mean harmonica as a younger man. Lost interest in it though. Didn't make much sense in here.

Andy Dufresne: Here's where it makes the most sense. You need it so you don't forget.

Red: Forget?

Andy Dufresne: Forget that... there are places in this world that aren't made out of stone. That there's something inside... that they can't get to, that they can't touch. That's yours.

Red: What're you talking about?

Andy Dufresne: Hope.
