Visible crew/equipment: In the crushing room at the end of the film, Strahm is trying to open the box where Hoffman is. As it's descending into the ground, on the side of the box you can see the feet of a crew member with white sneakers moving around. It is not Strahm's feet: he's wearing black boots. No slow-mo is required.
Visible crew/equipment: In the opening murder scene watch when the man is stood outside the connecting train car doors, there is a shot from behind, moving in on him, and if you look out of the left window you can see a set of yellow ladders.
