We already know that the second season of CSI Las Vegas will lose its main iconic male character: Gil Grissom (William Petersen).
William Petersen producer of the series
These new episodes will bring together a clever mix of characters from the original series and new protagonists. If William Petersen had only signed for one and only one season, and therefore will not return in season 2, he will remain producer of the series.
His partner Jorja Fox, who plays Sara Siddle since season 1 of the original series, and present in the reboot, may for his part eventually return. The new arrivals of the reboot -Paula Newsome, Matt Lauria, Mandeep Dhillon and Mel Rodriguez- will certainly be back.
A priori, TF1 is on the move to broadcast this new version of Experts in France. To be continued.
