The Terminator spawned a beloved sci-fi action franchise that expanded beyond movies to comic books, video games, and TV shows. Arnold Schwarzenegger has become synonymous with the series, portraying the iconic, gun-toting T-800 cyborg. In the 1984 original, he starts as a villainous presence before the character becomes a hero in Terminator 2, which is often regarded as one of the greatest action movies of all time.
