“The Beloved,” unlike “Sentimental Value,” really is one of those movies about the making of a movie, like “Day for Night” or “The Stunt Man.” It’s a meaty and enjoyable entry in the genre, one that updates it to the present day, when it’s not as easy as it once was for a director to bully a cast and crew (and Esteban, make no mistake, is something of a bully).
