For Petersen, the decision to return to the world of “CSI” and the character of Grissom was an easy one. “The idea of being able to come back into the land of science, I thought, was really a great opportunity,” he told reporters during a Zoom panel with the Television Critics Association, noting that working with forensics on the show had given him an appreciation for science. “I didn’t want to carry a gun at all,” he said. “The idea of being able to work with just the mind, as an actor, was a challenge and a great opportunity to grow as a performer.”
As for how the new show will be different from the original, Petersen pointed out that 20 years have passed since “CSI” launched, which will inevitably lead to changes. Plus, the cast is full of new characters as well. Joining Petersen and Fox in the revival are Paula Newsome as Maxine Roby, the head of the Vegas Crime Lab, as well as Matt Lauria, Mandeep Dhillon, and Mel Rodriguez.
“CSI: Vegas” premieres Wednesday, Oct. 6 at 10/9c on CBS.
