>>The movie you refer to was THX-1138 which if memory serves was the ID # of the storm trooper that Luke Skywalker pretended to be as he emerged from the Millenium Falcon. Not to mention that THX is Lucas's sound technology. Makes you wonder what's up with that.

The original said 'THX-1138' the first year.... and I thought that was great that he had plugged the old movie... then later,... pooofffffhhh.... gone! Changed.
