The first clear shot I've seen of the bloodied prisoner's face whose hands the robots were taping up. And it was THX all along? Since he looked fine before and after his trial, it makes the robots even more sinister if they beat the crap out of you, and then have you healed and cleaned up for your public appearance.
And what is that thing behind the kids? Yet another type of robot?
