The Uber Morlock is Jeremy Irons.
Of course he is played by Jeremy Irons, but I like to think the character himself really is the actor Jeremy Irons who miraculously survived underground and evolved into the cerebrally enhanced Morlock leader 800,000 years hence. The story about how the moon got knocked out of orbit was a lie
Given the Artistic License – Physics entry on the film page, Alex may have been right about science going too far for the wrong reasons. He had no idea about how nuclear bombs work nor how the moon would be affected. So he took their explanation at face value and just didn't have a chance to investigate or think about it.But what if that story the soldiers gave him was a lie to coverup an experiment gone wrong? Or a case of Gone Horribly Right that was a deliberate act to create the Morlocks?
Vox is responsible for naming the Eloi and Morlocks.
Since The Time Machine and its various adaptations exist in-universe in this film, and Vox is shown to be able to accept outside information and offer his own opinions on them, he saw how similar the new human offshoots were to the characters from the story, and since he was already forming the basis for their use of English, they took the terms and accepted them.There are two time travelers.
While Alexander Hartdegen is busy discovering time travel in New York, the original character from the book independently works it out in London. Each man travels to 802,701 and encounters distinct colonies of the Eloi. Alexander falls in love with Mara and the other guy falls for Weena. The post-London Eloi are also tormented by the Morlocks. Although we aren't told the fate of the London time traveler and Weena in this continuity, Alexander is the one who ultimately destroys the Über Morlock (and presumably, the rest of their global empire).Vox taught Mara to speak English
Even in its written form, "the stone language" would not have lasted as a living language for more than 800,000 years. Vox is a direct link to the old world. Although the other Eloi seem afraid of Vox, thinking that he is some sort of ghost, Mara is fearless and eventually realizes there is more to his story. So one day, she starts going there to visit him and he teaches her to speak the language (but apparently not to read it). Since the other Eloi don't go to the ruined library, she teaches the language to everyone. The film is a Meta Sequel. Alexander got the idea to build his machine from the HG Wells novel.
We already know the novel exists in-universe. Related to the above trope of Vox naming the Eloi and Morlocks, perhaps Alexander has read (or at least heard of) the novel. The novel was published in 1895, which gives Alexander several years to have been exposed to it before the completion of his time machine in 1903. After Emma's death, he might have either discovered or recollected the concepts from the novel and began his work on bringing its titular device to life in his desperation to save his ill-fated fiancee.
