I really don't want to speculate about what affect the shootings had on Batman's box office but i do know that almost everyone i spoke to about it was spooked and they were hesitant to see it opening weekend as a result.
I don't blame them and i'm in no position to question their motives, that's their decision.
It made about another 20 mil on monday and 17 mil on tues., those are very strong holds . It's just shy of 200 mil after 5 days of release, according to BOM, that's about 45 mil behind Avenger's pace after the same time period .
Really couldn't say what happens from this point and i know it's not important right now but for the hell of it, it should break 500 mil. People will get over their apprehension i'm sure.
