Fox has had second thoughts about moving The O.C. to Thursday nights (opposite CSI and Will & Grace) next month, when it returns from its seven-week hiatus. Instead, the network will air the second half of the hit primetime sudser's first season on Wednesdays at 9 pm (opposite ABC's The Bachelor), beginning Oct. 29. In other scheduling news, Fox is moving Bernie Mac to Sundays at 8:30 pm, where it will replace the talk show-within-a-sitcom The Ortegas, which has now been benched to midseason. Bernie kicks off its new season on Nov. 9.
