Oh yeah, the influences of German Expressionist directors of the 1920's and early 30's including Fritz Lang, F.W. Murnau, and Robert Weine are all over Burton's 1980's and 90's films. The appearance of the Jack Nicholson version of the Joker specifically is, of course, a reference to Conrad Veidt in Paul Leni's film adaptation of Victor Hugo's "The Man Who Laughs." Batman Returns has even more of these references than Batman (1989) does. I'm positive I'm not giving any new information here lol, I just wanted to add my two cents.
