A producer of HBO’s “Game of Thrones” and other major works reportedly praised the movie “My Son” Hunter at a recent advance screening in Los Angeles but says he can’t tell colleagues due to Hollywood’s pernicious cancel culture, giving credence to “My Son Hunter” producer Ann McElhinney’s remarks about how “Hollywood would never make this movie. It doesn’t fit their narrative, so that’s why we had to get the American public to fund it.”
