Something weird is happening here. It looks like time has stopped!
Notice how in the top gif the Cyberman seems to be moving really fast. But in the bottom gif (which is slowed way down) you can see that besides the weapons shooting and the camera angle changing, no one is moving.
Literally no one changes there positions or reacts at all despite the fact that a Cyberman walks right past them.
Maybe this is just a camera trick to show super speed, but either way I suspect our upgraded friends have a new trick or two!
