Hugh Grant once again shows his range as an actor in A24's new horror thriller, Heretic. There was a time when Grant was most known as the romantic comedy lead, but the British actor has had a renaissance of sorts in the last few years. Heretic tells the story of two Mormon missionaries who turn up at the house of a peculiar man, to spread the word about their religion. However, they end up fighting for their lives in a twisted game, and end up questioning the legitimacy of their religious beliefs.
