A year ago, M. Night Shyamalan scored a surprise hit with his movie Split about a teenager named Casey (Anya Taylor-Joy) abducted and held hostage by Kevin Wendell Crumb (James McAvoy) , a man suffering from dissociative identity disorder. The end of the film had a surprise: a direct link to Shyamalan's comic superhero homage Unbreakable that led to an announcement that his follow-up film Glass would further connect the two movies In its presentation of Hall H in San Diego Comic-Con today, Universal Pictures released a full trailer of the film.
The trailer features Dr. Ellie Staple (played by Sarah Paulson), a psychiatrist who specializes in "those individuals who believe they are superheroes", addressing Bruce Willis Unbreakable character David Dunn, Kevin Crumb several personalities, and Mr. Glass by Samuel L. Jackson. The three characters have met in a hospital under their skeptical supervision to receive treatment. The main character of Jackson seems to be in the center of the film, saying that he wants the rest of society to know that there are people like him, and to know the Beast, the monstrous personality that became the main antagonist of Split – for its own sinister purposes.
While Split only insinuated that the movie and Unbreakable would share a universe, Glass pushed that point home, with Shyamalan observing during the panel that he would gather his suspense and comic films for "the first superhero movie completely punished". Glass will be launched on January 18, 2019.
