Johnny Galecki ,"The Big Bang Theory"
Johnny Galecki had a long-standing role on the beloved show Big Bang Theory. He played Leonard on the show, and Big Bang was an empire that made all of its costars millionaires. Like Parsons, Galecki still racks up around $10 million a year in passive income. And the show's spinoff, "Young Sheldon," just got renewed for another season. Spock would be proud.
