Prologue
The X-Men have decided to make a musical movie, and it features villains too. I point this out because you will hear and see the characters reference to the entire story as a movie. They wanted to do this in order to give their fans something new and exciting to see. While I know this concept isn't exactly 100% original, I think it has its own uniqueness to it. I also recommend that you play the music while you sing because it helps to visualize. Besides, there won't always be words, and imagining the characters dancing and stuff is always easier when you've got the music in the background. Also, the perspective is that of someone watching the movie, so if you see something like "the camera moves" you'll know what it means.
