Heather Graham (The Hangover) and Mary Lynn Rajskub (24), each twice-nominated for SAG Awards, will guest star in Season 7 of the hit Showtime comedy series Californication. Graham will play a woman from Hank's (series star and executive producer David Duchovny) past whose arrival upends his life, while Rajskub will play a neurotic writer. They join recently announced guest star Michael Imperioli (The Sopranos). Production on the seventh season's 12 episodes begins later this month for premiere in 2014 on Showtime.

On television, she starred in Scrubs, Emily's Reasons Why Not and Arrested Development. She earned SAG nominations for her work in Bobby and Boogie Nights.

Rajskub is best known for her SAG-nominated performance as expert computer programmer Chloe on the long-running hit Fox series 24.
