William Earl Spoiler alert: The entire plot of “Pearl” and “X” will be discussed in this article. Who knew a church dance tryout would result in one of the year’s strongest film monologues? That’s the case with “Pearl,” Ti West’s twisty, hallucinatory ode to Technicolor-era film. It’s the prequel to this year’s grimy porn slasher “X,” in which Mia Goth played an aspiring XXX actress as well as a makeup-laden, nearly-unrecognizable elderly woman named Pearl who ended up killing most of the film crew staying on her farm. In the latest film, Goth takes on a third role of Pearl as a young woman.
