Before getting into "Contract," S5E5 of 'Billions,' cocreators Brian Koppelman and David Levien discuss diving into Bobby Axelrod's childhood; the greatness of the episode's director, Adam Bernstein; and the costume and wardrobe department's effect on the show; they also explain some obscure references and shout-out some guest-cast performances (0:30). They next speak with actress, writer, and comedian Eva Victor about her signature style-satire videos; the dynamic relationship between her character, Rian, and Winston; how Eva's part came about; set stories; and more (36:06).
