The Unbreakable trilogy, also known as the Eastrail 177 Trilogy, is an American superhero thriller and psychological horror film series. The films were written, produced, and directed by M. Night Shyamalan. The trilogy consists of Unbreakable (2000), Split (2016), and Glass (2019).
All of the films feature the character David Dunn. The series has been noted for its differences to more traditional superhero movies, with Shyamalan’s work referred to as “the first auteur shared superhero universe”. It is the first superhero franchise that is written and directed by one person, in comparison to other popular films in the genre. Shyamalan has noted that while it is based on comic book superheroes, and refers to comic books, it is not actually derived from comic book material itself. In contrast to most superhero films, the series is also generally grounded in reality, and is seen as a deconstruction of the superhero genre. The series is thus considered to be a unique take on the superhero genre.
The filmmaker has stated that the films are origin stories, of people with unique gifts, with the intent being to acknowledge that every person has something special about them. Unbreakable has been labeled the first grounded superhero film, while Split has been called the first solo supervillain origin story, and Hollywood’s first stealth sequel. Although the series is slated as a trilogy, Shyamalan mentioned that he would be open to a continuation if the inspiration came to him. (wiki)
