After two decades and three spinoffs, the CSI franchise is back to where it all began in Sin City for CBS series CSI: Vegas. Even better, original CSI: Crime Scene Investigation stars William Petersen and Jorja Fox are in the cast.
The original CSI ended with a feature-length finale event in 2015, but Fox told TV Insider that her and Petersen’s characters haven’t changed much during the intervening years. “I think it’s hard to teach an old dog new tricks,” she says. “I think you will see Sara and Grissom the way that we remember them. At the same time, I think we both hope that we have evolved.”
With the return of CSI: Vegas, we’re checking in with CSI’s Season 1 stars and two later recruits who also returned for the new series.
