NBC Universal President Jeff Zuckerpraised Crichton as a "modern-day Renaissance man," adding, "He was aphysician, writer, director and producer -- few people have done so manythings so well. As creator and producer of NBC's ER, he helped changethe face of televised drama." In recent years, Crichton broke withestablished scientific opinion on the issue of global warming, claiming inhis last novel, State of Fear, that scientific fears that it wasbeing created by pollution generated by mankind were groundless.
