“Do you ever think about just killing him?” Amanda (Olivia Cooke, “Me, Earl and the Dying Girl”) asks her kind-of new friend Lily (Anya Taylor-Joy, “The Witch”) in a memorable scene from psychological thriller “Thoroughbreds,” the feature debut of writer-director Corey Finley. As Amanda casually uncorks a bottle of wine, the two teens first discuss the main subject of the movie — their plan to kill Lily’s stepfather Mark (Paul Sparks, “The Greatest Showman”).
