To change the emphasis, if not the topic, I was musing with some co-workers today about how Christopher Nolan and the other creative folks who made this movie might feel about last night's events, as well as about the commercial repercussions of this awful event.
I do not believe with one cell of my being that Nolan or anyone else involved with this movie did anything wrong or has any reason to blame himself. This was clearly a heavily-planned attack, and it seems to me that Holmes chose this movie mostly because it was a midnight premiere - there were fewer employees and customers to worry about than any normal night showing, and it would definitely attract a packed house. I have no reason to think the subject matter itself inspired him to do this, and even if it did, there is nothing gratuitously violent or exploitative about either of the first two Nolan Batman films - in fact I think they are at the apex of quality for superhero movies.
I greatly admire Nolan - I think he is the most talented filmmaker of his generation. His ability to make movies with great intelligence and quality, ranging from eccentric indie fare to giant-budget action spectaculars, is really unrivaled (Steven Soderbergh has done kind of the same thing, but with, IMO, a lower level of quality). I have seen all his films and enjoyed all of them a great deal.
All of that being said, I'd have to think this must feel surreal and queasy for Christopher Nolan and company. James Holmes had apparently colored his hair to resemble the Joker, and told the police he was the Joker. Obviously the persona he adopted - a menacing figure in black, armed to the teeth and operating in darkness - had much in common with Batman. I think if I'd made this movie, and I were as bright and thoughtful a person as Nolan seems to be, I'd be feeling very mournful and weirded-out today.
It also occurs to me that Warner Brothers and everyone else involved with this movie will likely take a completely undeserved financial hit from all of this. It seems to me this shooting will already deter a tiny percentage of people from going to the theatre, and given the enormous volume of potential theatre viewers of this movie, that probably means millions of dollars. If, God forbid, there were a copycat incident, you'd expect that number to increase exponentially. I don't mean to be coarse or insensitive but it's interesting to think of a huge company as another real victim in this tragedy.
