Darren Aronosky's other film, pi, was also shot on Coney Island, although the coaster isn't visible there. I thought of mentioning this when I saw the movie, but because of it being a mature type movie of questionable material, IMO, I let it slip unmentioned.
At the end of Requiem, the way the Cyclone is shown, it's credited in the movie as a star almost. Just watch the credits if you haven't already, it's all there.
As for it being shown in school? I'm open-minded and all, that's pushing it, IMHO. It's not for the faint of heart as someone put it(especially the original theatrical release, unbelievable!), and sure, there's lessons, but lessons in the dark, you know?
The book, even further out there. There are just some people that will not be able to watch this just to see the Cyclone, IMO, and I loved the movie, it's just surrealism in a real form, hardcore.
