Speaking (as many in this thread have) of one film's poster ripping off the style of another... Am I the only one who recognizes this ESB poster as a pretty blatant rip-off of this "Gone With The Wind" poster?
As far as the new Trek poster resembling the last Dark Knight poster goes? Chances are both resemble countless movie posters that proceeded them. One can see that as being "terribly derivative and unoriginal" or can just as easily see it as "paying homage to the great traditions of the past".
Also, one can say that pretty much all movie posters by Jock (a/k/a Mark Simpson) look pretty much like every other movie poster he's ever done, as he tends to create images from "negative space", not only in his film posters, but in his comic work as well.
