I was thinking about that interview with Mark Hamill from back in '83 where he talks about 'another plane of existance' etc in the ST. On face value it appears to suggest Luke may be appearing as a force ghost. However i wonder if given that statement and given what we have seen in the existing trilogies we can extrapolate a bit more from that - a gradual movement from a physical focus to a spiritual one? PT: The force is referred to by its physical context - midichlorians. Only hints about the afterlife/being one with the force. The battles mostly concern manufactured biological beings and droids. OT: The force is referred to in its spiritual context. Force ghosts/afterlife become much more apparent. Battles concern humans/aliens fighting each other - with some input from Obi wan as a force ghost ST...? Full nature of the force is revealed. Ability for force ghosts to interact with physical world is expanded / developed? Battles concern physical beings and force ghosts? Possibly on 2 different planes of existance, possibly not. An early ROTJ screenplay mentioned Ben and Yoda returning from the netherworld - perhaps this idea may yet be used (though presumeably not Ben and Yoda?) Thoughts anyone?
