And if Hal goes with Sebastian Shaw for his ROTJ edit, Hayden Christensen’s ROTJ body could be up for grabs without it being a repetition of the previous imagery (though whether some technical wizardry to use that for Ben is beyond my know how - I leave that all of you. Hence why I stay quiet and just read usually. But it’s exciting!)
