During the scene where the resistance first appear, the storage rooms in the distance are the set for the medieval short film Best Man Wins.
The first resistance member to be killed by the machine, Lee Sheard, also provided the voice performance for the machine.
During the scene where the resistance fighter runs out of the farm house, the wall light is still painted blue from where it doubled as the entrance to the police station in the feature film The Colour of Everything and the rest of the farm was the professors house in that film.
