Aidan Gillen returns to the podcast (first time: Episode 40). You know him from some of the most beloved shows of the century: “Game of Thrones,” “The Wire,” “Peaky Blinders,” to name a few. Now he stars in the Irish Neo-noir film “Barber,” where he plays a private investigator hired by a wealthy widow to find her missing granddaughter. He talks about why he doesn’t look at the lines until the day before shooting, how his latest venture on the stage affected his work, why he still doesn’t like rehearsal for film, what bothers him about the idea of an “actor-centric” production, and much more. Back To One is the in-depth, no-nonsense, actors-on-acting podcast from  Filmmaker Magazine. In each episode, host Peter Rinaldi invites one working actor to do a deep dive into their unique process, psychology, and approach to the craft.  Follow Back To One on Instagram
