 In the last fight scene David Mattey (qv), who plays as the Super  Drone, was wearing a suit of armor and prosthetic appliances on his  face and full colored eye contacts, the type that surround the whole  front of the eye, greatly restricting your vision. To add to the  difficulty the scene was filmed in the rain and at night. David  Mattey ended up being a better swordsman than his stunt double, who  ended up sitting the scene out.
