Lorenzo Semple Jr established the tone of the 1966 Batman television series, which fixed the character as camp in the public mind for two decades and which later filmmakers spent enormous effort undoing.
He then wrote The Parallax View and Three Days of the Condor, two of the defining paranoid thrillers of the 1970s, which is an unlikely pivot from the same writer.
He also wrote Flash Gordon and the Bond entry Never Say Never Again, and the camp and the paranoia turn out to be two sides of the same distrust of institutions.
