Matt Reeves’ The Batman had a couple of twists and big reveals, and one of them regarding Gotham City’s criminal underworld ended up paying off a joke from Christopher Nolan’s The Dark Knight. After the failure of Joel Schumacher’s Batman Forever and Batman & Robin, the Caped Crusader made a successful return in Christopher Nolan’s Dark Knight trilogy, with the second installment, The Dark Knight, considered one of the best superhero movies ever made. The Dark Knight saw Batman (Christian Bale) dealing with the Joker (Heath Ledger), who arrived at Gotham City to unleash chaos while Harvey Dent (Aaron Eckhart) tried to dismantle organized crime.
