yup was at work when i heard it. This was preatty good planned by the guy. He came in while there was a gunfight on the screen and with all the 4D cinema effects we hear about nobody suspected a thing when smoke greanede was thrown in and people relized something was wrong when it got too loud and people around them started to panic when they got shot.
I don't know about the motive but now it might be a really ahrd time for those responsible for the movie as it will be connected with the massacre. I wonder was it a mad act, some kind of revange or an act that someone plans to profit from.
