This is the first episode in which the iconic "NA-na-na-na-na" sound effect was used, but it wasn't used to accent one of Steve Austin's moves. It was used to accent the attacks of the Major Sloan robot.
When Steve kicks the car upside down, on the side of the car we can see the shadow of the chain and metal bar used to flip it.
After Steve has dropped the steel girder, it bounces & wiggles as if made out of rubber.
In the beginning, the robot's makers are showing the robot a photograph that is different from the closeup photo of Steve Austin that the robot is viewing in the next shot.
