The fact that you have to skip through minutes of video to find single lines of dialog really shows you how weird this game was. I always got the impression that Kiefer was expensive, so they got him in once and once only. So when they went to change things around and cut things up, they had no way of recording the new lines and had to work around what they already had in the can.
Complete speculation on my part, but something always felt really off with there being so little dialog from the main character the second Kojima got his big Hollywood star wank fantasy fulfilled.
