Remember everything we said about "Django Unchained", and all the things we've come to expect from Tarantino movies? Maybe we should add "unforgivable continuity errors" to the list. Don't tell the man himself that we've noticed this, we've heard he gets a little angry.
Marvin Nash is a heck of a guy. He can take a licking and keep ticking, and he can also apparently perform contortionist tricks that would have Houdini up out of his seat and applauding. Here he is in one scene with his hands cuffed behind his back. Once the assault is over, they're cuffed in front of him. Either he's been hit so hard that his entire spine flipped inside out, or the director wasn't paying attention to detail when they went to finish the scene. We'll let you make your own minds up.
