Their newborn son is rescued by an American ambulance driver and grows up in the United States under the name Christopher Jones . Sought out by the lookalike son of James Filby, Jones goes to England to collect his inheritance, leading ultimately to George's journals, and the Time Machine's original plans . He builds his own machine with 1970s upgrades and seeks his parents in the future . Pal also worked on a detailed synopsis for a third sequel, which was partly filmed for a 1980s U.S. TV special on the making of Pal's film version of The Time Machine, using the original actors . This third sequel, the plot of which does not seem to fit with Pal's second, opens with the Time Traveller enjoying a happy life with Weena, in a future world in which the Morlocks have died out . He and his son return to save Filby in World War I . This act changes the future, causing the nuclear war not to happen . He and his son are thus cut off from Weena in the far future . The Time Traveller thus has to solve a dilemma--allow his friend to die, and cause the later death of millions, or give up Weena forever . </Li> </Ul>
