Petersen & Helgenberger Return For 2-Hour ‘CSI’ Finale, Danson Joins ‘CSI:Cyber’

CBS announced today that CSI: Crime Scene Investigation will end with a two-hour TV movie, as previously reported. Original stars William Petersen (Gil Grissom) and Marg Helgenberger (Catherine Willows) are set to reprise their roles in the series-ending storyline, which will air on Sunday, September 27. “We’re actually a little misty-eyed about this one,” CBS Entertainment President Nina Tassler said. “It was a series that was so important to this network, and we will have an epic finale to start the season.”

Additionally, it was announced that current CSI star Ted Danson (DB Russell) would join the cast of CSI: Cyber going into the show’s second season. He will be a series regular, but there is no further information about how else the cast might be affected by the “retooling” mentioned here. “It’s going to be a season of very big events,” Tassler revealed.

You can find some tweets after the jump, including one from Helgenberger!
