When it comes to Christopher Nolan's Dark Knight trilogy, the director is touted for his handling of Batman's rogues' gallery. Villains such as Liam Neeson's Ra's al Ghul and Heath Ledger's Joker had nuance, making statements on society and how anarchy was a natural way of resetting order. Even Cillian Murphy's Scarecrow had a significant message on the fragile human condition and how fear affects people's psyches – heroes or not.
