Hehe! That fan art is a scream. Sagan himself probably would have liked it...I don't know if he was a SW fan per se, but in "The Demon-Haunted World," the book he co-wrote with his wife Ann Druyan, he mentioned the famous misuse of "parsec" as a unit of time, rather than a unit of distance, but then he said that the film was "in many other ways exemplary."
