There were tons of subtle references in Joker you might have missed, but one of the not-so-subtle ones was a direct callback to The Dark Knight, when the Joker trumphantly rides in the back of a cop car while looking out the window. A Twitter user pointed out the side by side Joker shots, in case you "didn't catch the reference," which of course prompted the rest of Twitter to point out the REAL scene that this shot might've been referencing. Here are some of our favorites.
