All shots of Ham freeing the prisoners from the workroom are mirrored:
Ham's blaster switches from his right hand to his left; the power cell on his blaster switches from the left side to the right side, and all prison uniforms have orange stripes on their right arm instead of the left.
During and after Kino Loy's address from the prison command centre, there are several cut scenes of the prisoners' escape. As they climb the stairs, the sound of their shoes can be heard and as some of them clamber up the gantry, shoes can be seen even though according to the plot they should have bare feet.
The Narkina 5 Prison console guard is poorly equipped in that he cannot see the room that he controls. He is in control of the doors (a lever on the console) he is in control of the lift and he is in control of the electrification of the floor. Yet he needs to rely on the other guards for clarification of circumstances ("How's it looking out there, what's going on out there") The levels have windows looking down on each workroom yet the console guard doesn't have a view from a window.
