Occupying the same January release window that Split found so successful earlier this year, Glass will be released on 18 January 2019, worldwide.
Presumably, the hope is that Glass will be able to capitalize on the fact that the first month of the year is usually a quiet one at the box-office, like so many other movies have done before it.
There are currently only a handful of films set to open in that same month: Ad Astra, a sci-fi adventure starring Brad Pitt; Pigeon Impossible, a family animation; Playmobil: The Missing Piece, an animation based on the Playmobil toy; and The Nightingale, a World War II drama.
A Brad Pitt sci-fi adventure is bound to draw attention, but based on how similar movies that put a veteran actor in a fantasy scenario - like George Clooney's Tomorrowland - have performed, Glass shouldn't have anything to worry about.
The threequel will be written and directed by Shyamalan, produced by Shyamalan, Jason Blum, Ashwin Rajan and Marc Bienstock, and will have Steven Schneider executive producing.
