Who wrote the CSI pilot episode?

Anthony E. Zuiker wrote the pilot episode of CSI: Crime Scene Investigation.

The episode, titled “Pilot,” introduced the Las Vegas crime-lab team and established the series’ forensic-procedural format. Zuiker was the show’s creator, and the pilot was directed by Danny Cannon. It first aired on CBS on October 6, 2000.

Zuiker’s pilot follows several investigations, including the apparent suicide of Royce Harmon, which is exposed as murder, and cases involving drugging and theft. The story demonstrates the show’s signature pattern: investigators combine laboratory science, physical evidence, and detective work rather than relying solely on interrogations.

A common mix-up is confusing the pilot’s writer with its director or later executive producers. Danny Cannon directed the episode, while Zuiker is the credited writer. The pilot also introduced major characters played by William Petersen, Marg Helgenberger, George Eads, Gary Dourdan, and Paul Guilfoyle.
