Saw V (2008)

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.

Jigsaw: Hello Seth, I want to play a game. Right now, you are feeling helpless. This is the same helplessness you bestowed onto others. But now, it's unto you. Some would call this karma, I call it justice. Now you served five years of what should have been a life sentence, for murder. A technicality gave you freedom, but it inhibited you from understanding the impact of taking a life. Today, I offer you true freedom. In thirty seconds, the pendulum will drop far enough to touch your body. Within sixty seconds, it will cut you in half. To avoid the pendulum, all you have to do is destroy the things that have killed... Your hands. You must insert your hands and push the buttons to start the devices before you. Your bones will be crushed to dust. Will you destroy the things that have taken life in order to save one, Seth? Make your choice.

Trivia: Patrick Melton and Marcus Dunstan, the writers of both "Saw IV" and "Saw V", have a cameo in the flashback of Hoffman being kidnapped and meeting Jigsaw for the first time. When Hoffman is about to get on the elevator right before getting kidnapped, Dunstan is the second man to exit the elevator (he is in black and has a beard), right after the snobbish woman. Melton is the tall man who exits the elevator last before Hoffman enters.

Question: The second trap, they had to break jars open that were on the ceiling and get into the safety chambers, but there were "only three" for four people... Those were some pretty long, tall chambers. Couldn't the two smallest people share a single chamber, and all four survive? Especially since they look tall enough for two people to lie down right on top of each other.
