I've watched the movie again yesterday and I wanted to take a good eye on the conclave scene 'cause there were many actors and actions so I thought that there might be something unfamiliar.
After couple of minutes I've found 2 bloopers!
Take a good look at these pics and tell me if this is true:
Here you can see a camera guy on the right shooting all these gangs who are running from cops
I'm not sure for this, but on the left - is this whole crew equipment for cameras and stuff?
