Two Original 'CSI' Stars Have Already Left 'CSI: Vegas,' But Now Two Others Are Reuniting

CSI: Vegas is a follow-up series to the beloved CBS series CSI and several original cast members have been involved with the show!

Two of the original cast members from CSI starred in season one of the new series, though they have already left the show. Now, two other original cast members will be reuniting in season two.

CSI creator Anthony Zuiker previously hinted about the returns in an ET interview back in October.

“I will be personally lobbying to bring somebody [specific] back from CSI, if we get a [season 2] pickup,” he said in the previous interview. “I think the fans would like to see some familiar faces. And if we do get a pickup, and we have a sit-down about what season 2 looks like, I’ll definitely be making a case for bringing familiar faces back, yeah.”
