If there is one writer who regularly nailed high concept [and did it over and over again] it was Michael Crichton. He was one of the first writers to write a story about a scientific and military response to a plague hitting the U.S. [Andromeda Strain]. Not to mention the only guy talking about space probes bringing back plagues. One of the first writers to address how organ harvesting could go really REALLY wrong [Coma*]. Was the writer who took the concept of cloning and said, Forget cloning sheep and humans, let’s clone dinosaurs [Jurassic Park]. He took on the Japanese/American business clash [Rising Sun]. Looked at sexual harassment from the perspective of a man being sexually harassed in the workplace instead of from the [much more common] perspective of a woman [Disclosure]. If there is one thing Crichton was continually capable of doing, it was looking at current trends and issues before anyone else did and not only nailing them before anyone else did, but taking them to their extremes.
“Extreme” and “first” define “high concept.” And while you don’t always have to be first, to be high concept you do have to go extreme.
