A 2008 superhero film directed by Christopher Nolan, based on the DC Comics character Batman. It is the second installment of Nolan's The Dark Knight Trilogy, starring Christian Bale as Batman and Heath Ledger as the Joker.
There's this great moment in one of those Dark Knight movies where the Joker has the opportunity to kill Batman and he says something like just kill me and the Joker says kill you. He's I don't want to kill you. You complete me.
""Steven Pressfield and Andrew Huberman refer to 'Dark Knight movies' in a discussion about having friction or competition to drive oneself. The specific quote about the Joker saying 'You complete me' is from 'The Dark Knight', making it the most relevant film in the franchise for this context."
