Judd Hirsch is interested in the pursuit of truth. That’s why he loved math as a student, that’s why he got a physics degree, and that’s why he has a civil engineering background. But he also learned to apply the pursuit of truth to his acting. Judd tells Marc why he always insists on conveying the truth about his characters, down to changing the characters’ names if they don’t feel right. They talk about his roles in Taxi, Ordinary People, Uncut Gems and as Marc’s dad on the show Maron, and how he uncovered the truth in all of those instances.
