Here's the final pistol designs that were seen in the film. That one on the right is a taser variant.
This was Carlyle's customised gold-plated, ivory gripped personal weapon that was filmed but didn't survive the edit. On the right is some of the patternwork I drew for the engraving, I referenced currency iconography and poison ivy cos he is rich and bad. Deep!
Here's pics of the final props. They were pretty functional with recoil and smoke puffin' out, really impressive. Those Weta dudes know what they're doing eh!
