** "It's alive!" was never said in the original book. In fact in the book Frankenstein didn't have any assistants to talk to. The original monster was more of a GeniusBruiser than the DumbMuscle that he is typically portrayed as.
** Electricity is used as the catalyst to bring the creature back to life in most modern portrayals. Electricity was never mentioned in the book's scene; in fact, Frankenstein makes a point of telling Walton he'll keep how he created the monster a secret. Wiki/TheOtherWiki states the electric use can be traced to the 1931 movie of Frankenstein.
* CreatorBreakdown: Many literary historians consider the monster's creation scene in Frankenstein to be an allegory on childbirth. Not long before writing the book, Mary Shelley had given birth to a premature, illegitimate child who lived only days. Victor Frankenstein's misshapen, partly-formed 'monster' is created in 'filth' and when first brought to life is jaundiced, as most premature newborns are. This allegory may be less obvious to us because most movie adaptations don't follow Shelley's text that closely and turn the creation of the monster into a more scientific and less earthy event than Shelley imagined.
* OneHitWonder: Only one of Creator/MaryShelley's novels is well-known today: ''Frankenstein, or the modern Prometheus''. Although she was taken very seriously in her day, nowadays it's either ''Frankenstein'' or being the wife of Creator/PercyByssheShelley (even though it was her efforts after his death that kept ''him'' from being considered a OneHitWonder)...
