The Suspense!
While we’re still on this scene, we might as well talk about the elephant in the room. What in the world happened to Jack’s suspenders? In one shot, he’s handcuffed to a pipe and sporting a pair of classy suspenders. In the next shot, where Kate hits Leo in the arm with the ax, his suspenders vanish.
What sort of sorcery is this? Well, it’s not sorcery at all. It’s, yet again, another instance of how shot-splicing can go wrong. It would’ve been impossible for Jack to remove the suspenders since his hands are cuffed up. Also, even if he could, why would he care so much about them?
