'The Dark Knight' connection in 'Joker: Folie à Deux' is laughably bad

Joker: Folie à Deux is an unfortunate hodgepodge of references to better, more interesting films, including musicals like The Umbrellas of Cherbourg and The Band Wagon. Now, we can add Christopher Nolan's The Dark Knight to that mix, as Joker: Folie à Deux's final act seemingly hints at the origins of Heath Ledger's take on the Joker, for which he posthumously won an Oscar for Best Supporting Actor.
