That's the best argument I've heard for keeping Shaw in the ending scene, cap. Lucas' explanation that Anakin truly died when he became Darth Vader and therefore his ghost would look like Hayden is a stretch, and if its a matter of choice of what to appear as, why wouldn't Obi-wan and Yoda choose to look younger (thank goodness Lucas doesn't think like that)?

Since its technically a hallucination of Luke's or he chooses to see them as he knows them, Shaw as Anakin makes sense. He's never seen a picture of his father, how could he imagine what he looks like (and don't tell me, "The Force!")?

Thanks, 005, but I think I did not fully convey the abstraction I was trying to describe.

The way I see it, Luke is sensing the presence of Ben, Yoda, and Anakin with the Force, not with his eyes, so it doesn’t matter whether he knows what Anakin looked like as a young man. The question is, in this moment of celebration after the destruction of Death Star II, when Luke “sees” Ben, Yoda, and Anakin, which Anakin does he see?

If Luke sees a hot-headed young man who was jerked around by the Jedi Council and the Chancellor of the Republic, then we should see Hayden Christensen.

If Luke sees a loving father who didn’t realize he was still capable of love until it overwhelmed him and he turned on his master, sacrificed his own life, and brought down the Galactic Empire to save his son, then we should see Sebastian Shaw.
