I’ll admit, whatever grade it was where I learned about Greek mythology, I must not have paid that close of attention. So prior to seeing Christopher Nolan’s The Odyssey, my understanding of the story was vague at best and heavily influenced by the Coen brothers movie O Brother, Where Art Thou? That said, I know about the sirens — everyone knows about the sirens. Along with the cyclops, the sirens are one of the most famous parts of The Odyssey. Yet when I saw Nolan’s movie, I was surprised by just how little screen time they occupied. It was so little, in fact, that I wondered if Nolan cut anything out of the original story.
