Los Angeles ? Up from CBS comes a-bubblin’ crude, with the network developing a reality series based on the old “The Beverly Hillbillies” sitcom.

CBS is planning to cast a weekly half-hour series that will chronicle the lives of a rural, lower-middle class family as they move into a luxurious Beverly Hills mansion.

The project is tentatively titled, “Real Beverly Hillbillies,” the trade newspaper Variety reported Wednesday.

A maid and personal assistants will be among the indulgences afforded to the family during a one-year stay in California. Participants also will be able to earn money each week as part of the contest.
