Continuity: In the beginning during the riot, a man with a sign reading "The end is nigh", can be seen shot at. The sign gets several gunshot holes, but as the man falls down the holes are gone. Submitted by Mortug

Revealing: In the beginning, during the riot outbreak, there is a scene with a soldier being pulled down from climbing a fence. In the next shot as the crowd is pushing forward, you can see a concrete road block tip over. If you look closely at the bottom of the block, you can see that it's not a real concrete block, but a prop made of wood planks and grey painted rubber. Submitted by Mortug
