Joker director Todd Phillips has revealed the five movies Joker fans need to watch to understand the influences for his DC standalone film. These are the films that Phillips and his co-screenwriter Scott Silver drew from the most for their gritty, more realistic interpretation of the iconic supervillain. And there’s not a Batman movie among them.
In my review of Joker, which I gave a 10 out of 10, I said: “Clearly drawing its spirit and style from classic ‘70s and ‘80s films like Taxi Driver, The King of Comedy, A Clockwork Orange, and Dog Day Afternoon, director Todd Phillips’ Joker presents a Gotham City that is unmistakably a stand-in for the hellish New York City of the era.”
