This movie is basically a retelling of another story. When the camera first pans the shelves of the Botany Bay it stops and centers on one book on the shelf in particular.....Moby Dick. That is what this movie is about. Khan is Ahab, The Enterprise is Moby Dick. At one point in the book the whale is circling Ahab's ship on the ocean. At one point in the movie the Enterprise is circling the Reliant (Khan's ship) in the Motara Nebula. Ahab had a scar up one entire side of his body given to him by an encounter with the Whale. At the end of the movie Khan has a burn mark/scar up one side of his body as well. Not to mention that Khan quotes from Moby Dick throughout the movie. The last quote he utters is one that Ahab uttered "From Hell's heart, I stab at thee, for hate's sake I spit my last breath at thee."
