Other mistake: When Marty returns to 1985 from 1885 the time machine is destroyed by a train. What is strange is that not only does the train not stop (which is mandatory in the event of an accident) but there is also no reaction from people nearby, such as those in the vehicles waiting to cross the track at the level crossing. Later, when Marty returns to the site with Jennifer, there is still no sign of police officers or other officials.

Back to the Future Part III (1990)
Plot summary
Directed by: Robert Zemeckis
Starring: Christopher Lloyd, Michael J. Fox, Mary Steenburgen, Lea Thompson, Thomas F. Wilson, Elizabeth Shue
Though Doc asked Marty not to come back for him, Marty does go back anyway, because he and the 1955-Doc find out that Emmet Brown was killed shortly after the writing of the letter (by Mad Dog Tannen, the great-grandfather of Biff).
Right after the time-jump, the DeLorean is attacked by Indians who put an arrow to the gas tank, the fuel goes away.
Doc finds a way to solve that: they must kidnap a train and accelerate with that above 88 mphs.
Doc saves the new teacher of the town, Clara Clayton, who was supposed to die, and falls in love with her.
Trivia: When filming the scene where Marty is being hanged from the clock tower, Michael J Fox agreed to really hang from the rope. Whilst filming, Fox held the rope away from his throat with his hand. At one time he wasn't holding the rope and was really being strangled. The film crew didn't realise, they just thought it was really good acting, until he passed out.
Question: Is "Googolplex" an actual word?





Chosen answer: Yes. A "googol" is the number 10 raised to the 100th power, or a 1 followed by 100 zeroes. A "googolplex" is an even larger number - 10 raised to the power of a "googol", or represented as 1 followed by a "googol" zeroes.
