Joe Chill - he killed batmans parents! he was hired by Lew Moxon, who could show up too, it would be interesting to see christopher nolan dig into batmans past in this movie
also, that dude died in Batman Begins. he was shot by some mobster before Bruce was gonna go up and shoot him in the courthouse.
if you're in a big city, do you think everybody in the city will recognize you?
not sure what u mean here. if i saw a guy who looked exactly like Jay-Z on streets of new york wearing glasses and different hair, i'd say "hey Jay-z got some glasses and a haircut". or at least say "hey that dude looks exactly like Jay-Z". clark kent never gets called out for looking like superman. additionally, the people that he works with should at least know. i mean jimmy olson works with clark kent everyday and idolizes superman. how can he not see the resemblance?
they make the point that clark is so doofy that there's no way people could suspect him to be superman. but still, wouldn't people see that shit? if you over analyze everything though, it can take some of the joy out. you gotta suspend some belief sometimes to get into the story.
