When Cody Stokes decided to shoot “The Ghost Who Walks” in his native St. Louis, it wasn’t because he was trying to make the city itself a character or was set on showcasing certain regional icons. The Gateway Arch, for example, doesn’t really make an appearance. But Stokes did choose St. Louis as his backdrop with good reason — and for viewers who know the region well, there’s plenty of local imagery to enjoy over the course of the fast-paced, 106-minute film. In this conversation, Stoke joins host Sarah Fenske for a closer look at his feature-length directorial debut, which is now reaching a wide audience on Netflix.
