Actor Théodore Pellerin is a familiar face in Quebec, with critically acclaimed performances in films like “Chien de garde” and “Juste la fin du monde.” Now, he’s taken on his first major role in an American movie with the intense psychological thriller “Lurker.” It’s about a fan who plots and manipulates his way into the inner circle of a rising artist on the verge of stardom. Théodore sits down with guest host Talia Schlanger to talk about his portrayal of an obsessive fan, how he prepared for the role, and how he shed his dark character after the film wrapped.
