Kathleen Turner, Peter Gallagher and Diane Farr will appear on SHOWTIME's acclaimed comedy series Californication's third season, premiering later this fall.

Turner will play Charlie's (Evan Handler) tough, sexy boss/agency head with a thing for her newest employee in 10 of the season's 12 episodes, while Farr will take over as a sexy teacher's assistant who strikes up a naughty relationship with Hank (David Duchovny) in several episodes. Gallagher will play the dean of students who has a contentious relationship with Hank in 8 episodes.

"Californication" stars Duchovny as hedonistic novelist Hank Moody who struggles to raise his teenaged daughter (Madeleine Martin), while still carrying a torch for his ex-girlfriend Karen (Natascha McElhone). This season, Hank takes a new job as a professor at a major California university, while Charlie ditches his porn star agent life for a new firm.
