James Pattersonand Michael Crichtoncouldn't be more different when it comes to their respective bodies of work. Patterson is well known for his crime thrillers, while Crichton penned plenty of cutting-edge science fiction novels. However, both men have had their work adapted multiple times for film and television; Patterson's Alex Cross novels inspired Prime Video's Cross, and Crichton might rival Stephen King for the number of his books that have been made into movies, including Jurassic Park.
