Thanks to all of you. That's right, pixie_twinkle. It's a post that I wrote in my blog (http://www.retroklang.com/?p=642 ... sorry, it's in spanish) in wich I draw an imaginary circle that connects several things. That circle "starts" with Strauss' "Zarathustra" and, from that point to Nietzsche's "Also spracht Zaratustra", Alan Moore's "Miracleman" comicbook, "Superman" (the comicbook), "Superman" (the movie" and ends in the same pints in wich it started: Strausss' "Also spracht Zaratustra". I thought that Williams had this connections (except Moore's Miracleman, of course) in mind when he included the Strauss musical motiv. In a comment, someone expressed that the inclusion of the Zaratustra excerpt, that is obvious in my opinion (same structure, the same ascension to C major, very similar orquestal colours) might be a coincidence, and I doubted that. So I've asked your opinons . Macrea's answer is illuminating. The point is clear know: a Salkind's request of a resemblance to Kubrick's "2001". Again, thanks for your kind help, Ferre
