What to Know
Oscar-nominated filmmaker M. Night Shyamalan is using the defunct Allentown State Hospital for filming of "Glass."
The film stars Bruce Willis, Samuel L. Jackson and James McAvoy.
Shyamalan, who was raised in Lower Merion Township, began filming earlier this month in other locations in the Philadelphia region.
A vacant Pennsylvania mental hospital is the setting as M. Night Shyamalan's upcoming film Glass starts shooting there next week.
The film, starring Bruce Willis, Samuel L. Jackson and James McAvoy is the final chapter in a superhero trilogy that also includes 2000's Unbreakable and last year's surprise hit, Split.
The stars and others are expected to film at the former Allentown State Hospital starting Monday. The former psychiatric hospital was built in 1912 and closed in 2010.
Sharon Pinkenson, director of the Greater Philadelphia Film Office, says the set will be closed so stargazers won't have a chance to see the cast.
However, the cast has been spotted in different locations around Philadelphia. Shyamalan and Samuel L. Jackson were spotted at a Philadelphia 76ers' home game on Oct. 20, and Sarah Paulson, who will also be in the new film, tweeted about her time at Philadelphia restaurant Davio's.
Shyamalan, who was raised in Lower Merion Township, began filming earlier this month in other locations in Philadelphia and has been tweeting about the production process.
