What's a Film Projector? A film projector is a device that constantly strikes movie along a path so that each frame of the movie is stopped for a fraction of a second in front of a gentle supply.

As a result of a feature size movie is so long, distributors divide it into segments which might be rolled onto reels. A typical two-hour film will most likely be divided into 5 - 6 reels.
