This is how I learned about fire
My brother and I watched this movie on our own when we were kids (I don't remember if he finished it, but I certainly did), and ever since then I've always remembered one scene. In my recollection, a battle is taking place on the roof of a castle, and Joan entreats the enemy commander to surrender. Instead he throws himself into the lower recesses of the castle, which are consumed in flames. Joan pauses and says, "Death by fire is a horrible thing." My child mind had always remembered it as "Death by fire is a terrible thing," but same difference.
The way she said it left such an impression on me that I asked my mom what she meant by it. I don't remember what she said, but she was always have honest with me, so after that I had a vague knowledge of how incomprehensibly painful burns can be. And that scene hasn't just imbedded itself in my memory because it was traumatic, but because the character died that way willingly. I suppose it was the beginning of my understanding of how people can be so devoted to an ideal, in this case a notion of honor, that they would sacrifice anything for it. It's just odd to me that that scene is the one I remember, rather than Joan being burned at the stake at the movie's end.
