Gabourey Sidibe missed winning the Oscar for Best Actress, but she's already moved on: The Precious star is set to guest star in Showtime's new series The Big C, the network announced Tuesday. The show is a "dark comedy" about an affluent suburb in Connecticut, and stars Laura Linney as a teacher who's rebounding from cancer. Oliver Platt will play her husband, and Sibide a "smart-alecky" student in her class. The Big C will start shooting in May—but isn't set to premiere until late summer.
