What do Duane Allman, Dick Clark, Patrick Dempsey, John F. Kennedy, Roger Maris, Bobby McFerrin, the Oak Ridge Boys and Frank Sinatra have in common?

They’re among the 66,000 people owed a portion of the more than $25 million in unclaimed residuals SAG’s holding.

SAG has launched a “Get Your Money” campaign to hook up the recipients — or their estates — with the funds, asserting that it’s a “dilemma” because the guild doesn’t have correct addresses in most cases.

One of the more puzzling names on the list is the late John Megna, whose credits included Dill in “To Kill a Mockingbird” and the young Hyman Roth in “The Godfather Part II.” But he’s also the half-brother of Connie Stevens, current SAG secretary-treasurer.

SAG’s campaign comes in the wake of a move to settle a lawsuit by Ken Osmond over how it disburses foreign tax revenues to actors — which SAG maintains are different from the unpaid residuals. SAG asserts that it’s paid out $2 million of the $8 million of the foreign royalties.

SAG and WGA member Eric Hughes has accused SAG of masking the origin of “unpaid residuals” due to nonmembers, asserting that those funds have actually come through foreign royalties — even though SAG allegedly lacks the authority to collect those funds.

The foreign levies for U.S. creatives have been around for nearly two decades. They began to flow after U.S. signed the Berne Convention, which establishes the right of authorship for the individuals who create works of art.
