Wouldn’t it have been much better if George Lucas could have kept Darth Vader out of the trailer for Episode III so that his appearance in the film would be that much cooler? I mean everyone already knows he’s going to be in it, the trailer doesn’t show him actually doing anything, why is he there? It should have hinted at his presence. A shadow, or a sillouette. Lucas has the subtlety of a porn director. Consequently he may have the same talent for directing.
