When you step back it seems quite odd that strangers gather together in a big room with high ceilings to watch a movie projected onto a large screen. The most common aspect ratio for movie screens is 1.85:1 to 2.35:1. The filmmakers decide the aspect ratio of a film and preferences differ from director to director. Often larger epic films, such as Gladiator, Titanic, and Star Wars are filmed with the wider scope of 2.35:1 to create a sense of being larger-than-life. Smaller, more personal films tend to favor the less gigantic 1.85:1 ratio. (source) But what would be the actual size of an average movie screen? I would say 30-foot by 70-foot.
The average reflectivity of a movie screen is a Pearlescent 15%. To make a pearlescent or silver screen, a reflective coating is added to the matte white vinyl. A glass bead screen actually has thousands of tiny glass marbles embedded in a transparent coating on the surface of the screen. (howstuffworks.com)

Does the average movie screen absorb or reflect most of the infrared spectrum of light? And does the infrared spectrum harm the screen over time?

Randy does the movie project shoot infrared light? I’m not sure it does. (but i don’t know)
