A film 19 years in the making, M. Night Shyamalan's Glass serves as a merger between the director's 2000 hit Unbreakable (starring Samuel L. Jackson and Bruce Willis) and the 2016 film Split (starring James McAvoy).
As so much time has passed between Glass and the original film (released a year after Shyamalan's breakout blockbuster, The Sixth Sense), the production doubled as a reunion of sorts for its principal cast. That much is evident in the recently released behind-the-scenes look at the film shoot, culminating in the emotional wrap of several performers' final scenes; hugs and speeches abound.
