Some of these movies Nolan screened for the cast and crew of The Dark Knight before shooting. Others shaped casting decisions, performance approaches, and even Gotham’s architecture. These six films (and one TV series) helped define the tone, stakes, and emotional weight of arguably the most iconic superhero film of the 21st century.
1) Heat

The most obvious influence, Michael Mann’s Heat, was Nolan’s atmospheric and architectural blueprint. He screened the film for his cast and crew before shooting so that they could get a sense of the scale. In an interview with GQ, Nolan said, “Heat was very much an influence … [Mann] understands the grandeur of a city and how it can become a kind of epic playground.”
The parallels are everywhere, from Joker’s daylight bank robbery to the iconic interrogation scene. The duality between Batman and the Joker mirrors the tension between Pacino’s cop and De Niro’s thief, locked in a philosophical war across a vast city.
2) A Clockwork Orange

Stanley Kubrick’s A Clockwork Orange was one of the first references Nolan and Heath Ledger discussed when developing the Joker. Ledger later said in a conversation with MTV News that Alex in A Clockwork Orange was “a very early starting point” for the character, adding that they ultimately moved away from the reference.
Still, the influence is apparent in the film: the Joker’s theatricality, his sadistic sense of humor, and his hypnotic cadence all echo Malcolm McDowell’s Alex. Both characters turn ultraviolence into entertainment and just want to watch the world burn.
3) Cat People

One of Nolan’s more surprising reference points during production was Cat People, Jacques Tourneur’s gothic noir horror film about a woman who believes she turns into a panther when aroused. It might seem like an odd pick for a Batman influence, but its atmosphere is deeply relevant.
The film’s shadowy visuals, psychological tension, and sexual undercurrents mirror the noir touches Nolan added to Gotham. In The Nolan Variations, author Tom Shone notes that Nolan screened Cat People for the crew to help lock in the tone. The gothic dread, after all, is what so many fans and critics alike loved about this version of Batman.
