Trivia: When the trailer for The Time Machine was first shown, Alexander is looking at a futuristic city. When the movie was officially played in theaters, the scene was changed to a red sky with Morlock lairs everywhere. Originally, the futuristic city was to show that the Morlocks had been defeated and that the Eloi evolved. It was changed because Simon Wells felt that if the Eloi won and evolved, Alex would have no reason to go back and start a new life with Mara.
The Time Machine (2002)
1 video
Directed by: Simon Wells
Starring: Jeremy Irons, Guy Pearce, Orlando Jones, Mark Addy, Phyllida Law, Samantha Mumba, Yancey Arias
Continuity mistake: At the very beginning of the movie, the clock on the wall strikes three o'clock. In the next scene, when Philby reminds Alexander of his date with Emma, he tells Alexander that it's close to five.
Uber-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 machine to go back to save her?
Trivia: At the end of the movie, when Mrs. Watchitt is standing in the doorway, there is a picture of H.G. Wells hanging on the wall behind her.
Answer: When Alexander is travelling through time, he sees everything in his lab being removed very quickly, so the equations on his board were most likely erased and his journals were probably thrown away.
