In my book, Still Rock Water, my character, Liliha, wrote a song about Superman. You can listen to the video if you like. Christopher Reeve was one of my heroes because he never gave up trying to walk. After his role as the flying man that's quite a let-down. In the story, Liliha's song is taken up by a producer and used in a television program listing the terrible tragedies that happened to each actor who played the part listed below.
I'm not sure I believe in curses. Maybe the very act of giving them credence causes the effect. I remember the curse of Tutankhamen and all the following deaths after his tomb was discovered. Would these things have happened anyway? We'll never know. Each thing affects another. There's no going back.
