Billions season 2 episode 5 is titled “Currency”, after the main play of the episode which happens to be a highly delicate currency play. Currency, the word, when spoken by Damian Lewis manifest as Bobby Axelrod, is also one among the many rhythmic words you’ll hear from him this episode, pronounced in impeccable New York-ese. We probably shouldn’t keep harping on his believability in this role. After all, that’s why they call it acting, right? Where most acting is a well-developed form of impersonation and most non-native accents are a form of ventriloquism, what Damian does with Bobby, in terms of body and language, is something else entirely. Something that is neither simply impersonation nor just ventriloquism.
