Searl desperately asking Kaneda! What do you see?! What do you see?
What an epic scene that was, i had tears well up in my eyes, because i know something about being fascinated by the light of the Sun.
"For Searle and, to a lesser extent, Kaneda (Hiroyuki Sanada), salvation/enlightenment is achieved by “touching” the Sun. Searle demonstrates this conceit through his fascination with seeing as much light as he can. When Kaneda sacrifices himself to the Sun’s rays for the good of the mission, he turns towards the approaching wall of searing heat that will destroy him. At the moment of his death, Kaneda is calm, humble and seemingly embracing the great power that consumes him. Searle is intensely curious, repeatedly asking Kaneda over the radio “What do you see?” What Kaneda sees is his death, his eternal darkness, in the midst of light. What can you see when the retinas are overloaded by light? Too much light is ultimately blindness, while in the midst of darkness one heads for light. This paradox again reflects the film’s spiritual journey, a journey simultaneously into light and darkness."
