CSI is going out with a bang, bringing back William Petersen as Supervisor Gil Grissom and Marg Helgenberger as Asst. Supervisor Catherine Willows. The epic two-hour series finale will air September 27.
There’s also good news for fans of Ted Danson’s character, Supervisor D.B. Russell, as he’ll join Academy Award-winner Patricia Arquette on CSI: Cyber.
