Whereas Space Odyssey could be a grand display of Nietzsche’s ideas on recurrence, Moon is perhaps a quiet meditation from a more human perspective
Clone II learning wood carving from Clone I brings to mind this particular passage from Nietzsche: What, if some day or night a demon were to steal after you into your loneliest loneliness and say to you: “This life as you now live it and have lived it, you will have to live once more and innumerable times more; and there will be nothing new in it, but every pain and every joy and every thought and sigh and everything unutterably small or great in your life will have to return to you, all in the same succession and sequence—even this spider and this moonlight between the trees, and even this moment and I myself. The eternal hourglass of existence is turned upside down again and again, and you with it, speck of dust!”
Just as the starchild in the last scene of Space Odyssey could be a reference to Bodhisattva (菩萨), Clone II puts on his yellow sleeping suit and starts a new journey at the end of Moon. Let the adventure begin.
