realized it was too much for one movie so made SW out of the first third of the story.
I guess I believe that much.
Obviously, the Leia/Luke relationship wasn't fully planned out yet. Like most things,
a lot got changed during the process.
But, I definitely don't buy that the ultimate goal was make Anakin Skywalker's story
the focus of the entire saga. The OT is the story of Luke Skywalker, and it always
was, prior to 1999.
