Before diving into S5E3, "Beg, Bribe, Bully," 'Billions' cocreators Brian Koppelman and David Levien discuss real-life examples of billionaire feuds, script-to-screen changes, a stellar performance from the assistant director, guest cast members, obscure references, and more (0:40). Then they talk with author Ben Mezrich about his time in the writers' room as consulting producer for Season 5 of 'Billions' (32:44).
