When a movie projector is moved closer to the screen does image get smaller or bigger?

The image on the screen will get bigger if the movie projector is moved closer to the screen. This is because light from the projector travels in straight lines, and so the closer the projector is to the screen, the larger the area of the screen that will be illuminated by the light from the projector. Conversely, moving the projector farther away from the screen makes the image smaller.
