RIP Michael Crichton. I remember Jurassic Park totally sucking me in as a kid, wishing for a world where that could happen.

Michael Crichton, who helped create the TV show “ER” and wrote the best-sellers “Jurassic Park,” “The Andromeda Strain,” “Sphere” and “Rising Sun,” died in Los Angeles on Tuesday, his public relations firm said in a news release.

He “died unexpectedly,” the release said, “after a courageous and private battle against cancer.”

He was 66.
