My bad, there is only 1 book, either way, the book makes it official. I doubt they would change such a big detail like that and have discrepencies between the book and the movie. It's highly unlikely when looking at the many junior novels that I have read in the past before the movies come out. Usually big things like that arent changed. Cyclops dies, yeah it sucks, I hate it as well. But thats the spin the scriptwriters and studio wanted to take, I bet ratner had nothing to do with it really. People give the director too much credit, and alot less credit to the producers and scriptwriters and managers.
