Watchmen: Comparison to Film
When comparing the graphic novel Watchmen to the film, there is only one major difference that is distinguished between the two. In the graphic novel, Ozymandias (Adrian Veidt) plots to change the course of history by creating a giant squid that attacks New York City to fake an alien attack. This leads all the nations of Earth to cease their hostilities and unite at the height of the cold war.
In the film Veidt unleashes a series of attacks designed to mirror the energy beams created by Dr. Manhattan. This may seem a lot more reasonable, but ruins the great similarities between both of the movies. It almost seems like they did not want to go over budget by creating a large squid like creature to destroy all of New York City.
Everything within the film was very similar when comparing it to that of the graphic novel. All of the actors/actresses hired looked very identical to the characters shown within the novel, and costumes were also very accurate. Dialoguer was also taken from the novel and used as a script for the film itself. Some events may have been left out or altered, but this is because it would be too time consuming to leave all scenes the same length as the graphic novel applies.
