I seem to recall seeing a mockup at some point of the altered line in Ben’s hut that sounded perfect. Does anyone here know whose this was or where it can be found? None of the “I”s I’ve had time to try so far fit in very well.
To me, the movie only allows the reasonable inference that Ben is lying after the dramatic pause when Luke asks about how his father died. Before that point, the clear implication is that he’s telling him the truth which Owen has obscured.
