Über-Morlock: You built your time machine because of Emma's death. If she had lived it would never have existed, so how could you use your time machine to go back and save her? You are the inescapable result of your tragedy, just as I am the inescapable result of you.
Alexander Hartdegen (Guy Pearce) invents a time machine in the late 1800s that takes him 800,000 years into the future. There he discovers that mankind has evolved into two races: the Eloi and the Morlocks.
