The human marionette thing IS kinda cool... in a Nightmare on Elm St 3: Dream Warriors sort of way. Actually, those are darts stuck in his hands that are attached to wires.
... we used gaffer tape to attach the lines to his palms because it was the stickiest tape we had, but under the lights and his palms sweating profusely, we'd only get one or two takes before the tape would fall off. It was quite the pain in the butt.
EDIT: I should put these in some sort of context since they're kinda abstract. The first three pics are of a drill bit that protrudes out of the movie's antagonist and enters a certain bodily orifice. And the fourth pic is of the antagonist. Enjoy! ... and I look forward to comments / criticisms.
Here are some screen grabs of pick up shots just completed!
Production Update: We're just putting the final touches on the edit trying to make the action flow as smoothly as possible and the score is almost done! Two days to go!
