(just a quick note – this video is nsfw at all, so please don’t watch it in a public place if you are uncomfortable with sex scenes!)
The hands in Bound are agents of possession – conversely of desire, of destruction, of other people, of weapons. It is no surprise that the mob target people’s hands within the film, tying them up and cutting off appendages, for it is the hands within the film that hold power. They possess people, give sexual pleasure, hold guns, fix sinks, signal love, call for help. They are agents of occupation, holding onto whatever they have, signalling their own agency. No wonder then, when Caesar finds out about the romance between Corky and Violet does he target their hands – hands which act to castrate him through their sexual use.
The video essay also hints at the Grosz reading from a while back; that is, that the gun has been used as an extension of the arm, a prosthetic. We see this both in Violet’s and Caesar’s actions both within the video essay and the film – they are the only two characters who actually use the gun (despite Corky’s deployment of the weapon, she does not use it within the film). Whilst the hands need only been in their organic state to create and repair, there is a need for a prosthetic in order to actively do harm – a gun, a pair of pliers, etc. The hands then become the vessel in this sense in order for destruction to be wrought.
