Silent screen star Gloria Swanson received $2500 for her guest appearance in this episode -- a mere bagatelle by today's standards, but a veritable fortune back in 1966. The premise: Seeing Swanson moving her valuables out of her Beverly Hills home (she's planning to move to an even bigger mansion), the Clampetts mistakenly believe that she's being evicted. To save the actress from the poorhouse, the hillbillies cast Swanson in a "new" silent movie, filmed at Jed's own Mammoth Studios. "The Gloria Swanson Story" originally aired on November 30, 1966, as the 150th episode of The Beverly Hillbillies.
