British Filipino director Paris Zarcilla’s new horror film, “Raging Grace,” tells the story of Joy, a young mother and undocumented immigrant from the Philippines who cleans houses and struggles to save money for a visa. The film also shows her experience with racism, which comes in the form of indignities and microaggressions. Paris tells Tom about how his mother inspired the main character, how he didn’t intend for the film to be a horror when he first started writing it, and why he doesn’t want to teach anyone a lesson with this story.
