of course, the Laurence Olivier character in Marathon Man is a thinly veiled version of Dr. Josef Mengele, the death camp doctor. Read a biography of Mengele a few years ago, Mengele: The Complete Story, by Gerald L. Posner & John Ware... Strikes right at what people will do given the opportunity, the years of hiding in Argentina, Paraguay, and Brazil after the war, the essence of evil... And the Boys from Brazil portrays Mengele as a sort of campy superman. Ironically, both films came out around the end of his life.
Just read The Voyage of King Euvoran by the great Clark Ashton Smith, powerful use of both coined and real, exotic words.
