'Billions' producer Brian Koppelman

Writer and filmmaker Brian Koppelman talks with Recode's Peter Kafka about co-creating the hit Showtime series "Billions." Koppelman has made a habit of engaging with the show's fans online, but says that when he's writing new episodes, he has to completely unplug from the rest of the world and not think about how Twitter will react to the latest twists and turns. He also talks about the show's intense commitment to detail, including its frequent visits to real-life New York restaurants, and whether he thinks the viewers of "Billions" are watching for the characters or for "wealth porn." Plus: How Koppelman accidentally became a Vine star and why Wall Street power players are similar to experienced poker players.
