I know you can hear it repeating over and over in your mind. Darth Vader is coming =)
I have been waiting for this for a long time. The trailers on starwars.com have depicted well the transformation of Aniken. So many quotes from the origonal trilogy stand out in my mind,
Governor Tarkin: Obi-Wan Kenobi?
Darth Vader: He is here.
Governor Tarkin: What makes you think so?
Darth Vader: A tremor in the Force. The last time I felt it was in the presence of my old master.
Governor Tarkin: Surely he must be dead by now.
Darth Vader: Don't underestimate the Force.
Darth Vader: There is no escape. Don't make me destroy you. [pauses] Luke, you do not yet realize your importance. You have only begun to discover your power. Join me, and I will complete your training. With our combined strength, we can end this destructive conflict and bring order to the galaxy.
Luke Skywalker: I'll never join you!
Darth Vader: If you only knew the *power* of the dark side. Obi-wan never told you what happened to your father.
Luke Skywalker: He told me enough! He told me *you* killed him.
Darth Vader: No. *I* am your father
Continuity will be the key to this movies success. From what I've seen on the starwars site, it seems as though Lucas is going to re-create the first about 15 mins of Star Wars: A New Hope, in an attempt to make the series flow better, but only time will tell =)
Here are the movie posters for Star Wars: Epsode III Revenge of the Sith:
both posters also come in reprints (which are less expensive)
