The Twilight Saga began with the release of the first film, "Twilight," in 2008. The movie, directed by Catherine Hardwicke, introduced audiences to Bella Swan (Kristen Stewart) and her romance with vampire Edward Cullen (Robert Pattinson). The film's success led to the production of four more movies, each based on the subsequent novels: "New Moon" (2009), "Eclipse" (2010), "Breaking Dawn - Part 1" (2011), and "Breaking Dawn - Part 2" (2012).
