of the fine time-travel movie Looper,
with Bruce Willis and Joseph Gordon-Levitt playing a hit man from the future at different ages:
One irony about dystopian sci-fi and comic-book movies is that although leading men may be slightly East Asian-looking in the future, America's slums will apparently be mostly white, with everybody else black. Much like in The Matrix, Hispanics don’t exist in Looper’s vision of America in 2044.
