Glass is an upcoming American thriller film written and directed by M. Night Shyamalan. Shyamalan considers the film as the final entry of a trilogy of films which include two of his previous films, Unbreakable (2000) and Split (2016). Bruce Willis and Samuel L. Jackson will reprise their Unbreakable roles, while James McAvoy and Anya Taylor-Joy will return as their characters from Split.
While there was interest in creating a sequel to Unbreakable, Touchstone Pictures opted not to finance one due to the film's poor box office performance. Shyamalan set out on writing Split using a character he had written for Unbreakable but pulled from the script due to balance issues. Shyamalan realized the opportunity he had to create a trilogy of works, and adapted the ending of Split to establish the film as within the Unbreakable narrative. This included securing the rights to use Willis' Unbreakable character from Touchstone, with the promise of including them within the production and distribution of this third film alongside Universal Pictures should it be made. Split was a financial success, and by April 2017, Shyamalan announced that he had started the production process for Glass. It will be the final part of Shyamalan's co called "Eastrail 177 trilogy".
The film is scheduled to be released on January 18, 2019 by Universal Pictures in North America and by Walt Disney Studios Motion Pictures in international territories.
