Suggest a movie title for the following movie plot: In the year 1899, Dr. Alexander Hartdegen (Guy Pearce) is a young inventor teaching at Columbia University in New York City. Unlike his conservative friend David Philby (Mark Addy), Alexander would rather do pure research than work in the world of business. After a mugger kills his fiancee, Emma, he devotes himself to build a time machine that will allow him to travel back in time and save her. When he completes the machine four years later, he travels back to 1899 and prevents her murder, only to see her killed by a horseless carriage. Alexander soon comes to realize that any attempt to save Emma will invariably result in her murder through other circumstances. Distraught, Alexander travels forward in time to 2030 to discover if, by then, science has been able to solve his question of how to change the past, thus determining whether Emma's life can be saved. At the New York Public Library, a holographic librarian called Vox 114 insists that time travel is impossible, so Alexander continues into the future until 2037, when the accidental destruction of the Moon by space colonists renders the Earth virtually uninhabitable. When he restarts the time machine to avoid falling debris, he is knocked unconscious and travels to the year 802,701, at which point he regains consciousness and stops the machine. By now, the human race has reverted to a primitive lifestyle. Some survivors, called "Eloi", live on the sides of cliffs of what was once Manhattan. Alexander is nursed back to health by a woman named Mara, one of the few Eloi who speak English. One night, Alexander and Mara's young brother, Kalen, dream of a frightening, jagged-toothed face. The next day, the Eloi are attacked and Mara is dragged underground by ape-like monsters. The creatures are called "Morlocks" and they hunt the Eloi for food. In order to rescue her, Kalen leads Alexander to Vox 114, which is still functioning after 800,000 years. After learning from Vox how to find the Morlocks, Alexander enters their underground lair through an opening...
