— treadmill stuff

The treadmill was actually a treadmill modified to create a more natural walk for a green screen shot.  The front part was removed so that the controls would not be blocking the actor as they walked.  To help the actor keep balance there was a pole added to the one side that would not be facing the camera.  If they needed to they could lean on that pole to regain their balance.  The treadmill was painted compleately green so that just like the suit and a green screen it could be keyed out by the editor.
