Mortimer Sackler

Mortimer Sackler sits on Purdue's board as one of the family's elder statesmen, a patrician presence more concerned with the family name and its philanthropic gloss than with the pills bearing that name. He speaks in the clipped, entitled cadence of old money, treating scrutiny of the business as an irritant rather than a warning.

Rothman plays him without villainous flourish, which is the point — Mortimer's menace is procedural, all boardroom courtesy and inherited certainty that the family's judgment is simply correct. That calm, unbothered entitlement lands harder than shouting would, letting the show indict a whole class of quiet complicity through one unruffled old man.
