4. The Scarecrow Cameo
Though The Dark Knight stands on its own, Nolan very nicely weaves in a few crumbs that pick up from his first Batman film, 2005’s Batman Begins. One of those crumbs is the brief cameo by that film’s villain, Scarecrow, played by Cillian Murphy. To see him still attempting to be a villain, but to be oh so easily thwarted by Batman, really helps set the stakes for this second go-round.
