Mark Hamill had an A + reaction to the discovery of a long-suspected Star Wars: A New Theory of Conspiracy of Hope
There seem to be two different theories as to why this resizing is taking place. One of them is that changing altitude is just something Luke Skywalker does in the universe. It’s part of his character, though at no point in a movie is it questioned or brought up. The other, which is more meaningful in its own way, corresponds to the old Paul McCartney theory of the dead. There are actually two actors who play the role of Luke Skywalker. Although it has never been adequately explained who the other is or why they are being used.
