Fred Clark

Bald, dour character player from the Broadway stage, who first played heavies but soon established himself as a comic actor.

I DREAM OF JEANNIE · S3, E3

The Greatest Con Artist in the World

In Honolulu, Jeannie, promising not to attract attention, attends a press conference with Tony. The reporters learn she is wearing a scarab pin worth a fortune and headline the visiting heiress. Charles, posing as his employer, Mr. Vanderhaven, the richest man the world, arrives in a Rolls driven by Eddie. He invites Jeannie and Tony to his yacht, where Vanderhaven, a hypochondriac, is holed up in his cabin. Charles schemes to get the scarab, but Eddie worries that their boss will cut them out of his will. While Tony is working, Charles takes Jeannie to Idiot's Cove, a worthless strip of beach generally underwater. He touts it as a site for Tony's beach house but refuses to sell it. Jeannie finds uncut diamonds Eddie has sprinkled around. Charles confides that gems wash up with the tide. As a favor to Tony, he swaps the land for the scarab. Sure he is now rich, Charles tells off Vanderhaven, who fires him and cuts him out of his will. Jeannie is crestfallen when Tony tells her she was taken by the world's greatest con man, but consoles her with the diamonds she got out of the deal. Jeannie pops into Charles' cabin with a suitcase full of diamonds. She reports that huge gems are coming faster than trucks can haul the away. Charles insists on swapping back the scarab for the lead. Then Eddie finds Jeannie's diamonds are chocolates. Later, Jeannie and Tony lunch with Vanderhaven, served by Charles, now forever a slave to his boss. Touching her pin, Jeannie remarks that Charles is the second greatest con artist in the world.
