He wrote a series of Medical Novels under a fake name that enventually got made into the show E.R.

He also wrote a book that was his vision of the Beowulf story called Eaters of the Dead, which Became the Film The Thirteenth Warrior. The Rough Cut of the Film was also called eaters of the dead and followed the book closely, the final film is not as good supposedly as the authors cut.

The novel Jurassic Park was a spectacular work of real science fiction meaning there was actual science involved and Crichton delivered a thriller which was speculative fiction. Better than the movie. sequel book The Lost world was not as good and was a letdown when i read it. Anyhow the sequel movie was worse because it did not even follow the book. JP Lost World to me is equivalent to Jaws II.

The novel Spectre and Congo both good reads were horrible films.

By the time he got around to that time travel story that was made into a bomb of a movie he was washed up as a writer.

Even as a fan of Crichton's in the 90's now i realize just how overhyped his works are. His body of work is slim compared to other writers. If Spielberg did not make films of his books to make him an overnight celebrity would he have tried harder to write some more good books?

John Grisham wrote more novels than he did and had more bestsellers. That lawyer writer guy and his law thrillers. Still i Like Crichton Better.

Who are the new Speculative Science based science fiction authors to follow Crichton?

I am sure the guy called he sequel to Jurassic Park the Lost World because he was aware of the novel By Sir Arthur Conan Doyle of the Same name that starred professor challenger.

you know the famous quote from doyle's lost word preface. "I've wrought my simple plan. To give one hour of Joy. To the boy who is half a man, or man who is half a boy"lol.
