Sure is. 'Glass' takes inspiration from related comic books, adapting and bringing the story to the big screen. The characters and plot elements have their roots in the comic world.
The fragile glass in movies usually refers to glass containers or decorations. They may be made of different materials such as tempered glass, ordinary glass or ceramic glass, but they all have a certain strength and fragility. When the glass is subjected to external impact or vibration, it may break or crack, so it needs special protection. In some movies, fragile glass could also represent a fragile emotion or state that people could not help but resonate with.
The movie Glass is purely fictional. It was written and directed to present an engaging and thrilling storyline rather than being drawn from real events. The plot and characters are the imagination of the filmmakers.
