I think the shootings had a bit of an effect. There are segments of the US population that will believe everything the news media says, and there are people in the media blaming the movie for the shooting. Inevitably there are probably people out there that changed their mind on seeing TDKR. Heck, there are probably people planning to boycott the movie and try to dissuade others from seeing it now.However, I think the shooting will have little to no effect on actual Batman/Nolan fans. Those who are fans of BB and TDK will not be staying away from TDKR just because of the shooting. I think those who are saying that a $170m-$180m opening weekend would be disappointing had too high of expectations in the first place. I wish people would stop looking at record breakers like Avatar, and The Avengers and think every big movie is going to do that now.FYI: The Dark Knights OW adjusts to $174.7m, and I think anything over that would be excellent.
