The ‘CSI’ Cast, Then & Now (PHOTOS)
After two decades and three spinoffs, the CSI franchise is back to where it all began in Sin City for CBS series CSI: Vegas — and with a second season! Even better, after original CSI: Crime Scene Investigation stars William Petersen and Jorja Fox starred in the first season, Marg Helgenberger returned for the second.
“She’s wiser and more mature. But she still has that intensity and fortitude and stamina and doggedness in regard to solving a crime — especially if it’s something that touches her deeply,” Helgenberger told TV Insider of Catherine Willows now. “That would never change, I don’t think, as long as she has her wits about her and her physical strength.”
With the return of CSI: Vegas for its second season, we’re checking in with CSI’s Season 1 stars and two later recruits who also returned for the new series.
