Otto Düring

Otto Düring is a German billionaire and philanthropist whose foundation, focused on refugee aid, employs Carrie Mathison in Berlin. Urbane and idealistic, he believes his money and influence can do genuine good in a messy world. He is generous, media-savvy, and convinced his intentions are pure — which makes him easy to trust and easier to use.

Koch plays Düring with a smoothness that never quite curdles into smugness, so you believe both his sincerity and his blindness at once. The character works because the show lets his do-gooding be real and naive simultaneously, and Koch's calm, patrician warmth makes his gradual entanglement in events beyond his control feel like tragedy rather than folly.
