  • Gary Dourdan said he was "smitten" with this episode, despite initial disagreements with the writer. "I was really surprised, because the fellow who wrote it, Josh Berman, in the beginning, we were on each other's s*** list," he said. (October 19, 2003 - CSI Files)

  • Originally scheduled to air on October 16, 2003, but was replaced with a repeat at the last minute to avoid competition with the baseball World Series.

  • Josh Berman: "I am most proud of "Invisible Evidence". In the episode, the CSI team must race against the clock to solve a case. It was a chance to 'break the mold' in the way a story unfolds. Also, it was the first time we started an episode with a CSI on the stand. As a writer, it was exciting for me to see how our CSIs react in a sterile courtroom." (May 03, 2005 - CSI Files)
