Text: Many languages are spoken, or historically have been spoken, in the United States. Today over 500 languages are used by the U.S. population. The most commonly used language is English (specifically, American English), which is the de facto national language of the United States. Since the 1965 Immigration Act, Spanish is the second most common language in the country. The United States does not have an official language, but some state governments recognize specific languages. For instance, the state government of Louisiana offers services and documents in French, as does New Mexico in Spanish. There are many languages indigenous to North America or to U.S. states or holdings in the Pacific region. Hawaiian, although having few native speakers, is an official language along with English of the state of Hawaii. Alaska officializes English and twenty native languages.

Text: McG signed on to direct as the first two films were among his favorites, and he had even cast Robert Patrick (who played the T-1000) in his films. Though he was initially unsure about ''flogging a dead horse,'' he felt the post-apocalyptic setting allowed the film to be different enough so as not to be just an inferior sequel. The idea that events in Terminator 2: Judgment Day and Terminator 3: Rise of the Machines altered the future allowed them to be flexible with their presentation of the futuristic world. McG met with the series' co-creator James Cameron, and, although he neither blessed nor denigrated the project, Cameron told the new director he had faced a similar challenge when following Ridley Scott's Alien with Aliens. He maintained two elements of the previous films; that John is an outsider to the authorities, and someone of future importance is being protected, and in this film, it is Kyle Reese.
